Answer:

[tex]\frac{5}{2}[/tex]

Step-by-step explanation:

recall for a line whose equation is

y = mx + b,

the slope of this line is m

the slope of a line that is perpendicular to this line is -[tex]\frac{1}{m}[/tex]

in this case,

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

hence -[tex]\frac{1}{m}[/tex]=[tex]\frac{5}{2}[/tex]

The slope of a line that is perpendicular to the line represented by the equation y = -2/5x + 4/5 is 5/2 .

The slope of a line perpendicular to a given line is equal to the negative reciprocal of the slope of the given line.

Let the given line is y = mx + c , where the slope of the line is m and the y-intercept is c .

The slope of the line perpendicular to this given line is equal to -1/m .

Given equation of line is y = -2/5x + 4/5 .

The slope of the given line is -2/5 .

Thus, the slope of the line perpendicular to this given line is equal to

= -(-5/2) = 5/2 .

Therefore, the slope of a line that is perpendicular to the line represented by the equation y = -2/5x + 4/5 is 5/2 .

Answer:

3.86 (or 3.9)

Step-by-step explanation:

There's a logarithm function on a graphing calculator

8n + 12 +(-9) -(-6n)

12 + -9 = 12-9 = 3

8n - (-6n) = 8n + 6n = 14n

The equation becomes 14n + 3

The function that is graphed below is y = |x - 8| + 2.

Option A is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto-one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The graph of the function y = |x - 8| + 2 is a V-shaped graph with the vertex at the point (8, 2).

The function is defined as the absolute value of the difference between x and 8, plus 2.

When x is less than 8, the expression inside the absolute value bars, (x - 8), is negative, so the function becomes y = -(x - 8) + 2.

Simplifying this expression, we get y = -x + 10, which is the equation of a line with a slope of -1 and a y-intercept of 10.

This line goes downwards to the left of the vertex (8, 2).

When x is greater than 8, the expression inside the absolute value bars, (x - 8), is positive, so the function becomes y = (x - 8) + 2.

Simplifying this expression, we get y = x - 6, which is the equation of a line with a slope of 1 and a y-intercept of -6.

This line goes upwards to the right of the vertex (8, 2).

At the vertex (8, 2), the function takes the minimum value of 2.

Overall, the graph of the function y = |x - 8| + 2 is a V-shaped graph with the vertex at (8, 2), and two lines with slopes of -1 and 1 on either side of the vertex. The graph is symmetrical about the vertical line x = 8.

Thus,

The function that is graphed below is y = |x - 8| + 2.

Answer:

(m-2)(m+2)

Step-by-step explanation:

a²-b²=(a-b)(a+b)

let m be a and 2 be b

m^2-2²=(m-2)(m+2)

For this case we must factor the following expression:

[tex]m ^ 2-4[/tex]

According to the formula of difference of squares we have:

[tex]a ^ 2-b ^ 2 = (a + b) (a-b)[/tex]

We have to:

Hola! My name is Zalgo and I am here to help you out today. So, let's observer everyone's ratio and if it can be simplified, we can simplify ti to make it easier. Jasmine has 12:10, Aaron has 3:2, Lucian has 10:10 and Gretchen has 14:2. If we simplify Jasmines, for every 6 blue, she has 5 red (6:5). Lucian has an equal ration if we simplify it (1:1) and Gretchen would have 7 blue for every 1 red (7:1). So, the person with the lowest ration would be Lucian.

Answer:

The first one: f(x) = 2

Step-by-step explanation:

In this case, we can see that for ALL values of 'x' the value of y=f(x) doesn't change, it's the same. That's why the function represented by the graph is f(x) = 2.

Answer:

f(x) =2

Step-by-step explanation:

Looking at the graph, the value of y does not change.  y always equals 2

y=2

Since this is in function notation

f(x) =2

Answer:

The first one: y - 2 = -5(x - 2)

Step-by-step explanation:

Answer:

the function y – 2 = –5(x – 2) is linear.

Step-by-step explanation:

We need to find the correct option from provided options which represents a linear function

Since, the linear equation is in the form of y=mx+c where m is slope of line.

In first part y – 2 = –5(x – 2)

Simplify, the function

[tex]y -2 = -5x + 10[/tex]

Add both the sides by 2, in above equation

[tex]y = -5x +12[/tex]

This function is in the form of y=mx+c

so, this is a linear function

In second part x + 7 = –4(x + 8)

Simplify, the function

[tex]x+7= -4x+32[/tex]

subtract both the sides by 7, in above expression

[tex]x= -4x+32-7[/tex]

[tex]x= -4x+25[/tex]

add both the sides by 4x,

[tex]x +4x= 25[/tex]

[tex]5x= 25[/tex]

divide both the sides by 5,

[tex]x =5[/tex]

This is not in the form of y=mx+c

so, this is not a linear function

In third part y – 3 = y(x + 4)

Simplify, the function

[tex]y-3= yx+4y[/tex]

add both the sides by 3,

[tex]y= yx+4y+3[/tex]

This is not in the form of y=mx+c

so, this is not a linear function

In fourth part y + 9 = x(x - 1)

Simplify, the function

[tex]y+9= x^{2}-x[/tex]

subtract both the sides by 9,

[tex]y= x^{2}-x-9[/tex]

This is not in the form of y=mx+c

so, this is not a linear function

Therefore, the function y – 2 = –5(x – 2) is linear.

Check the picture below.

let's recall that a circle has a total of 360°, so the arcDCF is 360 - 266 = 94, and is the intercepted arc by the inscribed ∡DEF.

Answer:

y=mx+b

(6,6)    (3,8)

6m+b=6

3m+b=8

6m+b-3m-b=-2

3m=-2

m = -2/3

-2+b=8

b=10

y = -2/3x+10

I choose 12.

-2/3(12)+10

=2

so put x as 12; y as 2.

Answer:

We want to add an x value we have not used before. A function has EVERY X IN A DOMAIN going to ONLY ONE Y value.

6,3,9,7 are already used for x.

so you can put in x = 8 and y = 12 as an answer. That will work and show a function. There are also other answers.

Step-by-step explanation:

Answer:

The correct answer is D.

The correct identity Samuel should use is: D. (20 x 6) + (4 x 6) = 24 x 6

To find the total cost of ordering 24 lunch specials at $6.00 each, Samuel needs to compute 24×6.

The distributive property states that:

a×(b+c) = (a×b)+(a×c)

In this problem, we can break down 24 into 20 and 4, and then apply the distributive property.

This gives us:

24×6 = (20+4)×6

= (20×6) + (4×6)

Answer:

36 minutes

Step-by-step explanation:

In order to find how many minutes it takes to fill 675 bottles, we need to find how many bottles the machine produces in one minute.

To do so, we can divide 150 by 8, which would give us the total amount of bottles produced in one minute.

150/8 = 18.75

So, 18.75 bottles are produced in one minute

To find the total number of minutes it takes to fill 675 bottles, we can divide 675 by the number of bottles produced in one minute, which is 18.75

675/18.75 = 36

Therefore, it takes the machine 36 minutes to fill 675 bottles.

Given : Machine fills 150 bottles of water every 8 minutes

[tex]\mathsf{\implies Machine\;fills\;1\;bottle\;of\;water\;in\;\left(\dfrac{8}{150}\right)\;minutes}[/tex]

[tex]\mathsf{\implies Machine\;fills\;(675 \times 1)\;bottles\;of\;water\;in\;\left(675 \times \dfrac{8}{150}\right)\;minutes}[/tex]

Answer:

The correct answer would be B, Sometimes.

Step-by-step explanation:

Rational numbers are sometimes the natural numbers.

Rational numbers are the numbers that can be expressed as a quotient or fraction of two integers. Rational numbers can be in the form of decimals or natural numbers. Natural Numbers are the normal integers like 1, 2, 3, 4, etc. So the resulting numbers of any equation will give a rational number or a natural number. So it is so correct to say that rational numbers are sometimes the natural numbers.

Answer:

A'(-2, -3)  B'(0, -3)  C'(-1, 1)

Step-by-step explanation:

change the signs for the Y coordinates because you are reflecting over the X-Axis. so 3 becomes -3, and -1 becomes 1. leave the X coordinates unchanged.

The reflection triangle ABC over the x axis is A'(–2, -3), B'(0, -3), and C'(–1, 1).

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation

If a point A(x, y) is reflected over the x axis, the new point is at A'(x, -y).

The reflection of A(–2, 3), B(0, 3), and C(–1, –1) over the x axis is A'(–2, -3), B'(0, -3), and C'(–1, 1).

The required inequality would be 99x + 84 ≤ 1,150. so the correct option is C.

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

Given;

The cost of the shirt she bought = $ 84,

And the cost of each watch she bought = $ 99,

Now Suppose she bought x watches,

So, the cost of x watches = 99x dollars,

Also, her total spending = 84 + 99x

Since she has a total budget of $1,150,

That is her spending can not be exceed $ 1,150, ( or spending must be less than or equal to $ 1150 )

⇒ 99x + 84 ≤ 1,150

Hence the required inequality would be 99x + 84 ≤ 1,150. so the correct option is C.
