A line has a slope of -3/4 and passes through the point (–5, 4). Which is the equation of the line?
a)y=-3/4x+1/4
b)y=-3/4x+4
c)y=-3/4x-2
d)y=-3/4x-1/4

Answers

Answer 1

M = slope
If slope = -3/4, M = -3/4

y = mx + b ---> y = -3/4x + b

Now substitute the point (-5,4) to find b, and therefore the rest of the equation.

y = -3/4x + b
4 = -3/4(-5) + b
4 = 15/4 + b
0.25 = b

Therefore the answer is A, Y = -3/4x + 1/4

I'm not sure so :/

Answer 2

Final answer:

The correct equation of a line with a slope of -3/4 that passes through the point (-5, 4) is y = (-3/4)x + 31/4. However, none of the answer choices provided match this equation.

Explanation:

To find the equation of a line with a slope of -3/4 that passes through the point (–5, 4), you can use the point-slope form of the equation of a line, which is y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point the line passes through.

Plugging in our values we get:
y - 4 = (-3/4)(x - (-5))
This simplifies to:
y - 4 = (-3/4)x - (-3/4)*(-5)
Which further simplifies to:
y - 4 = (-3/4)x + 15/4

To find the y-intercept, we put the equation in slope-intercept form, y = mx + b, by adding 4 to both sides:

y = (-3/4)x + 15/4 + 4
y = (-3/4)x + 15/4 + 16/4
So the final equation is: y = (-3/4)x + 31/4

Looking at the answer choices, there is a mistake in the options provided because none of the options match y = (-3/4)x + 31/4. It's important to convey this discrepancy to the student.

For the equation x^2+3x+j=0 , find all the values of j such that the equation has two real number solutions. Show your work.

Answers

The solution is j<2.25, meaning all values of j less than 2.25 will provide two real solutions.

For the equation [tex]x^2+3x+j=0,[/tex] to have two real number solutions, the discriminant must be greater than 0. The discriminant, D, of a quadratic equation [tex]ax^2+bx+c=0[/tex] is given by [tex]D=b^2-4ac[/tex].

In this case, a=1, b=3, and c=j. Applying the values, we get:

[tex]D=3^2-4(1)(j)[/tex]

D=9-4j

For two real solutions, D>0. Therefore:

9-4j>0

To find the values of j, solve the inequality:

9>4j

j<9/4

Thus, all the values of j that satisfy j<2.25 will ensure that the equation x^2+3x+j=0 has two real number solutions.

how to write unit form for (2 tens 1 one) x 10

Answers

Numbers are arranged by their place values. Place values give a quantity of value to a certain digit in a number. Given a number, the rightmost number is the ones place, followed by the tens place, hundreds, thousands, ten thousands, hundred thousands, millions, ten millions, hundred millions, as so on and so forth. The place value of a certain digit is 10 times bigger than its adjacent digit to the right.

So for this problem, all you have to do is multiply the number of units of each place value, then multiple them all by 10.

(2(10) + 1(1))×10
21 × 10 = 210

Therefore, the number is equivalent and written as 210.

Which graph represents the solution to the system of inequalities?

x + y ≤ 4

y – x ≥ 1

Answers

ANSWER

The correct answer is C.

EXPLANATION

To find which set represents the solution set of the system of inequalities, the best thing is to graph the inequalities and locate the intersection of the solution region of the two graphs.

The given inequalities are,

[tex]x + y \leqslant 4 \: \: and \: \: y - x \geqslant 1[/tex]

Let us start with,

[tex]x + y \leqslant 4[/tex]

To graph this inequality, we first of all graph the corresponding linear equation,

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

using the intercepts,
[tex](0,4) \: and \: (4,0)[/tex]

We plot the above points and draw a solid straight line through them.

We test for the origin to determine which half plane should be shaded.

[tex]0 + 0 \leqslant 4[/tex]

[tex]0 \leqslant 4[/tex]

This statement is true, so we shade the lower half plane.

We repeat the same process to graph,

[tex]y - x \geqslant 1[/tex]

So we graph the corresponding straight line,

[tex]y - x = 1[/tex]

using the intercepts,

[tex](0,1) \: and \: (-1,0)[/tex]

We plot the intercepts and draw a solid line through them.

We test for the origin again to see which half plane to be shaded.

[tex]0 - 0 \geqslant 1[/tex]

[tex]0 \geqslant 1[/tex]

This statement is false, so we shade the
upper half plane.

The intersection of the two region is the region in option C of the graphs provided.

A car dealer recently sold five cars for the following profits: $10,126, $9,999, $12,398, $12,007, and $4,567. What was the mean for the profits of the sales?

Answers

Mean or Average is all of the sums divided by how many of the choices are there, so all of 10,126+9,99+12,398+12,007+4567=49097 and divided by all the choices you have which is 5 is 9819.4

Answer:

$9819.4

Step-by-step explanation:

We have been given that a car dealer recently sold five cars for the following profits: $10,126, $9,999, $12,398, $12,007, and $4,567. We are asked to find the mean for the profits of the sales.

Since mean is the average of numbers. So let us add all the profits and divide the sum of profits by number of cars.

[tex]\text{Mean for the profits of the sales}=\frac{10126+9999+12398+12007+4567}{5}[/tex]

[tex]\text{Mean for the profits of the sales}=\frac{49097}{5}[/tex]

[tex]\text{Mean for the profits of the sales}=9819.4[/tex]

Therefore, the mean for the profits of sales is $9819.4.

Nick has two more than twice as many quarters as dimes.. one fewer than three times as many nickels as dimes, and eight more pennies than dimes.. he has $7.37. How many of each coin does he have?

Thank you so much :)

Answers

Let's say we have x dimes.
This would mean we have:
(2x + 2) quarters,
(3x - 1) nickels and
(x + 8) pennies
The total value is 737 cents ($7.37)
We can thus say that if we multiply the number of each type of coin by the value of that coin and add it all, we will get 737, so we can write an equation:
10x + 25(2x + 2) + 5(3x - 1) + x+8 = 737
And if we tidy this up by multiplying out the brackets and collecting like terms, we get:
76x + 53 = 737
Now, solve for x:
76x = 684
x = 9
So by subbing into the expressions constructed at the start, we find how many of each coin we have:
9 dimes,
(2(9) + 2) quarters,
(3(9) - 1) nickels and
((9) + 8) pennies.
so... 9 dimes, 20 quarters, 26 nickels and 17 pennies.

If n = 8 and 16 • 2m = 4n – 8, then m = ?

Answers

Hello there! Thank you for asking your question here at Brainly. I will be assisting you today with answering your question, and will teach you how to handle it on your own in the future.

First, let's examine the question, and proceed to evaluate once we understand what we're dealing with.

"If n = 8, and 16 • 2m = 4n - 8, then m = ?"
This question is requesting for us to input the value for n, and then solve for m.

Here is our equation:
16 • 2m = 4n - 8

Let's plug in 8 for n.
Our equation should look like this now:
16 • 2m = 4(8) -8
First, let's get 4(8) by itself; Add 8 to both sides.
16 + 8 = 24
-8 + 8 = 0

Our equation is now:
24 • 2m = 4(8)
Multiply 4 by 8 to simplify the right side of the equation.
4 • 8 = 32

Now we have:
24 • 2m = 32

To solve for m, we need to isolate 2m and then divide both sides by 2.
Subtract 24 from both sides to isolate 2m.
24 - 24 = 0
32 - 24 = 8

Our equation is now:
2m = 8
Divide both sides by 2 to solve for m.
2m / 2 = m
8 / 2 = 4

Our final equation and solution is:
m = 4.
The value for m is 4.
I hope this helps!

Final answer:

The value of m is 0.75 when n = 8 and the equation 16 • 2m = 4n – 8 is satisfied, by performing simple algebraic operations to isolate and solve for m.

Explanation:

To find the value of m when n = 8 and 16 • 2m = 4n – 8, we first replace n with 8 in the second equation:

16 • 2m = 4(8) – 8

16 • 2m = 32 – 8

16 • 2m = 24

Now we divide both sides of the equation by 16 to isolate 2m:

2m = 24 / 16

2m = 1.5

Finally, to find m, we divide both sides of the equation by 2:

m = 1.5 / 2

m = 0.75

So the value of m that satisfies the given conditions is 0.75.

A city planner designs a park that is a quadrilateral with vertices at J(-3, 1), K(1, 3), L(5,-1), and M(-1,-3). There is an entrance to the park at the midpoint of each side of the park. A straight path connects each entrance to the entrance on the opposite side. Assuming each unit of the coordinate plane represents 10 m, what is the total length of the path to the nearest meter?

Answers

By definition, a quadrilateral is a two-dimensional figure that is composed of four sides. Since you are given with the coordinates of the vertices, the first logical thing to do is to plot the points in a Cartesian plane as shown in the attached picture. Next, find the midpoints of each side of the quadrilateral as denoted by the red dots. Then, create a line connecting the opposite midpoints which represents the length of the paths.

Our first solution is to find the midpoint of each sides. This is done by taking the average of each coordinate. The equation would be:

x,midpoint = (x₁+x₂)/2
y,midpoint = (y₁+y₂)/2

So, applying the equation:

midpoint jk = (-3+1/2, 1+3/2) = (-1,2)
midpoint kl = (1+5/2, 3+⁻1/2) = (3,1)
midpoint ml = (5+⁻1/2, ⁻1+⁻3/2) = (2,-2)
midpoint jm = (⁻3+⁻1/2, 1+⁻3/2) = (-2,-1)

Next, we find the lengths of the paths by using the distance formula:

d = √(x₂ - x₁)² + (y₂ - y₁)²

Distance between jk and ml = √(⁻1-2)² + (2 - ⁻2)² = 5
Distance between jm and kl = √(3-⁻2)² + (1-⁻1)² = √29
Total distance = 5 + √29 = 10.385 units

Since the scale is 1 unit = 10 meters, the actual total length of paths is equal to:

Actual Total Distance = 10.385*10
Actual Total Distance = 103.85 meters

Answer: The width of the peak depends on the Standard Deviation. The standard deviation is a measure used to quantify the variation or dispersion in the data set. If the standard deviation is low, this means that the set of data tends to be closer to the mean, then the width of the peak in the normal curve is small, for other part if the standard deviation is big, this means that the variation is big and the data set is more spread, this causes that the width of peak to be larger.
