The Tables Above Represent Data Points For Two Linear Equations. If The Two Equations Form A System,

Answers

Answer 1
Equation 1 slope: -x+4
Work: y2-y1/x2-x1: can be any points, points 0,4 and 4,0. 0-4/4-0= -4/4= -1x, 4 is y intercept the number that goes through Y which is 4 in this case.
Equation 2 slope: 1/4x-6 if you follow steps above you should get this as well.
Solution: Set both equations equal to each other to find solution.

-x+4=1/4x-6.
+x = +x
4=5/4x-6
+6= +6
10=5/4x
10(4/5)
X=8
Plug in x to any equation.
-8+4=-4 y=-4
Solution to both equations is 8,-4
Answer 2

The x-coordinate of the solution to the system of linear equations is 0.

To find the x-coordinate of the solution to the given system of linear equations, we need to analyze the data points provided for both Equation 1 and Equation 2.

Similarly, examining the data points for Equation 2, we notice that as x increases by 4, y increases by 1. This implies a constant rate of change and suggests that Equation 2 also follows a linear pattern. We can express Equation 2 in the slope-intercept form:

y = (1/4)x + b.

To find the x-coordinate of the solution to the system, we need to set the two equations equal to each other and solve for x.

Equating the two equations, we have:

-x + b = (1/4)x + b

By simplifying the equation, we can eliminate the b term:

-x = (1/4)x

Next, we can multiply both sides of the equation by 4 to eliminate the fraction:

-4x = x

Bringing all the x terms to one side, we get:

-4x - x = 0

Combining like terms, we have:

-5x = 0

Finally, we divide both sides of the equation by -5 to solve for x:

x = 0

Answer:

Part 1) [tex]y=-x^{2}[/tex]  ---> Translated up by 1 units

Part 2) [tex]y=x^{2}+1[/tex]  ---> Reflected across the x-axis

Part 3) [tex]y=-(x+1)^{2}-1[/tex]  ---> Translated left by 1 unit

Part 4) [tex]y=-(x-1)^{2}-1[/tex] ----> Translated right by 1 unit

Part 5) [tex]y=-x^{2}-1[/tex]  ----> Reflected across the y-axis

Part 6) [tex]y=-x^{2}-2[/tex]  ----> Translated down by 1 unit

Step-by-step explanation:

we know that

The parent function is

[tex]y=-x^{2}-1[/tex] ----> this is a vertical parabola open downward with vertex at (0,-1)

Calculate each case

Part 1) Translated up by 1 unit

The rule of the translation is

(x,y) -----> (x,y+1)

so

(0,-1) ----> (0,-1+1)

(0,1) ----> (0,0) ----> the new vertex

The new function is equal to

[tex]y=-x^{2}[/tex]

Part 2) Reflected across the x-axis

The rule of the reflection is

(x,y) -----> (x,-y)

so

(0,-1) ----> (0,1) ----> the new vertex

The new function is equal to

[tex]y=x^{2}+1[/tex]

Part 3) Translated left by 1 unit

The rule of the translation is

(x,y) -----> (x-1,y)

so

(0,-1) ----> (0-1,-1)

(0,1) ----> (-1,-1) ----> the new vertex

The new function is equal to

[tex]y=-(x+1)^{2}-1[/tex]

Part 4) Translated right by 1 unit

The rule of the translation is

(x,y) -----> (x+1,y)

so

(0,-1) ----> (0+1,-1)

(0,1) ----> (1,-1) ----> the new vertex

The new function is equal to

[tex]y=-(x-1)^{2}-1[/tex]

Part 5) Reflected across the y-axis

The rule of the reflection is

(x,y) -----> (-x,y)

so

(0,-1) ----> (0,-1) ----> the new vertex

The new function is equal to

[tex]y=-x^{2}-1[/tex]

Part 6) Translated down by 1 unit

The rule of the translation is

(x,y) -----> (x,y-1)

Answers

Answer:

[tex]y=-\frac{1}{7}x+\frac{37}{7}[/tex]

Step-by-step explanation:

Your equation is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.  Your line has a slope of 7.  In order to find the line perpendicular to this line, we have to take the opposite reciprocal of the slope.  The perpendicular slope to m = 7 is m = -1/7.  Now we go through x = -5 and y = 6 to find the new equation.

6 = -1/7(-5) + b gives us

6 = 5/7 + b and

b = 37/7

Therefore, the equation of the line perpendicular to your original line is

[tex]y = -\frac{1}{7}x + \frac{37}{7}[/tex]

Dorothy typed in an integer, hit the $?$ button, and saw an output of $13$. What are all possible integers Dorothy may have input?

Answers

Answer:

  {52}

Step-by-step explanation:

The calculator function appears to be ...

  f(x) = {3x -1, x odd; x/2 +1, x not divisible by 4; x/4, x divisible by 4}

The inverse of the first function is ...

  x = 3y -1

  (x+1)/3 = y . . . . (y must be odd)

For x = 13, this is 14/3, which is not an integer.

__

The inverse of the second function is ...

  x = y/2+1

  2(x-1) = y . . . . (y must not be divisible by 4)

For x = 13, this is 2·12 = 24, which is divisible by 4, so 24 is not the input value.

__

The inverse of the third function is ...

  x = y/4

  4x = y . . . . (y must be, and is, divisible by 4)

For x = 13, this is 4·13 = 52.

The only possible input value for an output of 13 is 52.

What is the approximate volume of a can that is 5 inches tall and has a 2.5 inch diameter?

Answers

Answer:

  24.5 cubic inches

Step-by-step explanation:

The formula for the volume of a cylinder is ...

  V = πr²h

A can with a diameter of 2.5 inches has a radius of 1.25 inches. Filling in the given values, the volume is ...

  V = π(1.25²)(5) = 7.8125π ≈ 24.54 . . . . cubic inches

The approximate volume is 24.5 cubic inches.

The volume of a cylinder is 24.54 inches³

What is Volume of cylinder?

The volume of a cylinder is equal to the product of the area of the circular base and the height of the cylinder. The volume of a cylinder is measured in cubic units.

We know that the volume of cylinder is

V = πr²h

Given that:

diameter = 2.5 inches

radius = 1.25 inches.

Height= 5 inches

V = π(1.25²)(5)

= 7.8125π

≈ 24.54 inches³

Hence, the volume of cylinder is 24.54 inches³

Your friend gives you a simple regression fit for predicting house prices from square feet. the estimated intercept is –44850 and the estimated slope is 280.76. you believe that your housing market behaves very similarly, but houses are measured in square meters. to make predictions for inputs in square meters, what slope must you use? (there are 0.092903 square meters in 1 square foot).

Answers

Answer:

  3022.08 . . . dollars per square meter

Step-by-step explanation:

The slope is multiplied by the factor that changes units:

  (280.76 dollars/ft²)×(1 ft²)/(.092303 m²) ≈ 3022.08 dollars/m²

Final answer:

To make predictions for house prices in square meters, you would have to multiply the given slope of 280.76 by the conversion factor of 1/0.092903, which will give an estimated slope of approximately 3017.9

Explanation:

The problem here is related to the conversion of units from square feet to square meters. Your friend gives you a simple regression fit for predicting house prices from square feet with an estimated intercept of -44850 and the estimated slope is 280.76.

Given that there are 0.092903 square meters in 1 square foot, a square foot equals to 1/0.092903 square meters. When you are making a prediction based on square meters rather than square feet, you need to consider this factor. This means the new slope would be calculated by multiplying the old slope with this conversion factor as:

Slope for prediction in square meters = Old slope * (1/0.092903) = 280.76 / 0.092903 = 3017.9 approximately.

Identify the reflection of the figure with vertices H(17,34), I(−5,10), and J(28,−14) across the line y=x.

Answers

Answer:

B

Step-by-step explanation:

Under a reflection in y = x

a point (x, y) → (y, x)

Given

H(17, 34 ) → H'(34, 17)

I(- 5, 10) → I'(10, - 5)

J(28, - 14) → J'(- 14, 28)

B represents the image coordinates of H, I, J

For the given figure with vertices H(17,34), I(-5,10), and J(28,-14) across the line y=x, the reflection will appear at H(34,17), I(10,-5), J(28,-14). This is because at y=x the reflection will have the coordinates with interchanged values.

Reflection at y=x:

Across y=x, the reflection will have interchanged coordinates.

that is (x, y) → (y, x)

For the given vertices across the line y=x,

H(17,34) → H'(34,17)

I(-5,10) → I'(10,-5)

J(28,-14) → J'(-14,28)

So, option (2) is correct that is H(34,17), I(10,-5), J(-14,28) which undergoes reflection across y=x.

So you can plot (6,0) and (2,0).

The vertex will lie half between x=2 and x=6... so it lays at (6+2)/2=4

We know that tangent of circle is a straight line that touches the circle exactly at one point. This point is known as point of tangency.

Upon looking at our given diagram, we can see that line segment RX touches circle A exactly at one point that is X. Line segment SX touches circle A exactly at one point that is X, therefore, line segment RS is tangent to our given circle.

Similarly, line segments SQ and TQ touch circle A exactly at one point that is Q, therefore, line segment ST is tangent to our given circle.

We can see that line segments RP and TP touch circle A exactly at one point that is P, therefore, line segment ST is tangent to our given circle.

AP is radius of circle, therefore, AP is not a tangent for our given circle.

Step-by-step explanation:

Part 1)

Let

x -----> the number of months

y ----> vertical jump in inches

step 1

Find the slope

we have the points

(0,16) and (2,17)

[tex]m=(17-16)/(2-0)=\frac{1}{2}[/tex]

The equation of the line in slope intercept form is

[tex]y=mx+b[/tex]

we have

[tex]m=\frac{1}{2}[/tex]

[tex]b=16[/tex] -----> the point (0,16) is the y-intercept

substitute

[tex]y=\frac{1}{2}x+16[/tex]

convert to function notation

f(x)=y

[tex]f(x)=\frac{1}{2}x+16[/tex]

Part 2) What is the equation of a line that contains the points (5, 0) and (5, −2)?

step 1

Find the slope

we have the points

(5, 0) and (5, −2)

[tex]m=(-2-0)/(5-5)=\frac{-2}{0}[/tex]

the slope is undefined

This is a vertical line (parallel to the y-axis)

therefore

The equation is

x=5

Part 3) Choose the equation that represents a line that passes through points (−1, 2) and (3, 1)

step 1

Find the slope

we have the points

(−1, 2) and (3, 1)

[tex]m=(1-2)/(3+1)=-\frac{1}{4}[/tex]  

step 2

Find the equation of the line into point slope form

[tex]y-y1=m(x-x1)[/tex]

Part 4) Jewels has $6.75 to ride the ferry around Connecticut. It will cost her $0.45 every time she rides. Identify the dependent variable and independent variable in this scenario

we know that

The independent variable is the variable whose change isn’t affected by any other variable (An example the age and time)

The dependent variable it’s what changes as a result of the changes to the independent variable (An example of a dependent variable is how tall you are at different ages. The dependent variable (height) depends on the independent variable (age))

Let

x ----> the number of rides

y ----> the total cost in dollars

In this problem

The independent variable or input is the number of rides

The dependent variable or output is the total cost

The correct linear function for Maryann's vertical jump is f(x) = ½x + 16. The equation of the line containing points (5, 0) and (5, −2) is x = 5. For the line through points (−1, 2) and (3, 1), the correct equation is 4x − y = −6, and in Jewels' scenario, the number of ferry rides is the independent variable, and the total cost is the dependent variable.

To write a linear function that models Maryann's vertical jump over 6 months, we need to determine the slope (rate of change) and the y-intercept (starting value). Given the increments of 1 inch over every 2 months, we can calculate the slope as 1 inch per 2 months or 0.5 (one half) inches per month. The starting value when the time (month) is 0 is 16 inches. Hence, the linear function is f(x) = ½x + 16, which corresponds to option A.The equation of a line that contains the points (5, 0) and (5, −2) is vertical because both points have the same x-coordinate. A vertical line's equation is x = some constant value, which in this case is x = 5, corresponding to option A.To find the equation that represents a line passing through points (−1, 2) and (3, 1), we can use the two-point formula or slope-intercept form, but by checking the given options, we see that option A fits the points: 4x − y = −6.In the scenario of Jewels riding the ferry, the independent variable is the number of rides she takes, and the dependent variable is the total cost, which depends on the number of rides taken. This corresponds to option A.

Which expression models the phrase “Wally mowed two more lawns than he mowed last week”?
n+2
n-2
2-n
2n

Answers

Answer: n+2

Two lawns more than last week so two more than something with n being that something is; n+2

For this case we have to:

n: It's the variable that represents the number of lawns that mowed Wally last week.

If you tell us as a fact that this week Wally mowed two more lawns, then we have the following expression:

h = 9 and k = -8

Step-by-step explanation:

An electrician charges a service call fee of $60 plus $55 per hour. Another electrician charges a service call fee of $20 plus $65 per hour. Set up and solve an equation to determine the number of hours, h, for which the cost would be the same for hiring both electricians.

Answers

Final answer:

By setting up an equation where the total costs for both electricians are equal and solving for h, we find that the number of hours for which the costs are the same is 4 hours.

Explanation:

To determine the number of hours, h, for which the cost would be the same for hiring both electricians, we set up an equation where both cost expressions are equal. The equation, which expresses the total cost for each electrician's services, is:

First electrician: Cost = $60 + $55h

Second electrician: Cost = $20 + $65h

We now equate the two expressions and solve for h:

$60 + $55h = $20 + $65h

$55h - $65h = $20 - $60

-$10h = -$40

Divide each side by -10: h = 4

Thus, the number of hours for which the costs are the same is 4 hours.

Final answer:

The number of hours for which both electricians would charge the same is 4 hours. We find this by setting up an equation based on their fees and hourly rates, solving this equation yields the result of 4 hours.

Explanation:

To determine the number of hours, h, for which the cost would be the same for hiring both electricians, we can set up an equation based on their charges. The first electrician charges a service call fee of $60 and $55 per hour. Therefore, the cost for the first electrician, C1, can be expressed as:

C1 = 60 + 55h

The second electrician charges a service call fee of $20 plus $65 per hour, which means the cost for the second electrician, C2, is:

C2 = 20 + 65h

To find when the costs are the same (C1 = C2), we set the two expressions equal to each other:

60 + 55h = 20 + 65h

Now we solve for h:

60 + 55h = 20 + 65h

55h - 65h = 20 - 60

-10h = -40

h = 4

The costs are the same when the electricians work for 4 hours.

Suppose that G(X) = F(x+ 9). Which statement best compares the graph of
G(x) with the graph of f(x)?

Answers

Answer: Option D

Step-by-step explanation:

By definition if we have a function F (x) and perform a transformation of the form

[tex]G (x) = F (x + c)[/tex]

Then it is true that:

If c is negative the graph of G(x) will be equal to the graph of F(x) displaced horizontally c units to the right

If c is positive, the graph of G(x) will be equal to the graph of F(x) displaced horizontally c units to the left.

Note that in this case the transformation is:

[tex]G (x) = F (x + 9)[/tex]

Then [tex]c = 9[/tex] and [tex]c> 0[/tex]

Therefore the graph of G(x) will be equal to the graph of F(x) displaced horizontally 9 units to the left

The answer is the option D.

ANSWER

D. The graph of G(x) is the graph of F(x) shifted 9 units to the left.

EXPLANATION

The given functions are F(x) and G(x).

The function, G(x) is obtain by translating or shifting the graph of F(x).

This translation is of the form.

[tex]G(x) = F(x+ 9)[/tex]

The '+9' within the parenthesis tells us that the shift is 9 units to the left.

Remember that for horizontal shift:

+ means a shift to the left.

The correct answer is D.
