Answer 2

Answer:

Answer:

m = -12.50, b = 1,500; The first option.

Step-by-step explanation:

To figure out the slope I used the equation, y1 - y2 / x1 - x2, to get the answer -12.50.

For the y-intercept ( b ), I just looked at the data table and where there was a zero in the X side of the Y there would be the, b, or y-intercept.

WILL GIVE BRAINLIESTThe graph below represents which system of inequalities? (attachment below)

A. y ≤ −2x + 3
y ≤ x + 3

B. y ≥ −2x + 3
y ≥ x + 3

C. y ≤ −3x + 2
y ≤ −x + 2

D. y > −2x + 3
y > x + 3

Answers

The answer is A.
We can first eliminate D since it uses these (<, >) signs and the lines are shaded, indicating the points on those lines are solutions.
We can also eliminate C because the y intercept in C’s lines is 2, while in the graph, they are both 3.
Finally, we can look at both inequalities on the graph and see that the shaded areas are both underneath the line. This means that y is less than the equation for the line, eliminating B
So, the answer is A

Write an equation in point slope form of the line that passes through the given point and the given slope m(-9,8) and m=4

Answers

Answer:

The answer is

$\huge y - 8 = 4(x + 9) \n$

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

From the question we have the final answer as

$y - 8 = 4(x + 9)$

Calculate the rent of a decreasing annuity at 8% interest compounded quarterly with payments made every quarter-year for 7 years and present value $78,000.

Answers

The general Formula for a decreasing Annuity is:
$P = ( ((1+i)^n -1)/(i (1+i)^n)) R$
For this example we have:
P = 78,000
n = 7*4 = 28
i = 8%/4 = 2% = 0.02

After substituting you can find value for R, rent.

a car is purchased for 26,000 after each year the resale decrease by 35% what will the resale value be

Answers

26,500 * .25 = 6625
26,500 - 6625 = $19875 ---------> Price after 1 year

Price after 2 years:
19875 * .25 = 4968.75
19875 - 4968.75 = $14,906.3 ---------> Price after 2 years

Price after 3 years:
14,906.3 * .25 = 3726.58
14,906.3 - 3725.58 = $11,179.7 ----------> Price after 3 years

Price after 4 years:
11,179.7 * .25 = 2794.93
11,179.7 - 2794.93 = $8384.77 ------> Price after 4 years, rounded to the nearest dollar = $8385

26,000 * 35% = 910. So $910 would be subtracted from 26,000 for each year
