The graph represents the balance on Harrison’s car loan in the months since purchasing the car. A coordinate plane showing Car Loan Payments. The x-axis shows Months since Purchase and the y-axis shows Loan Balance in dollars. There is a straight line that starts at (0, 7,000) and passes through (2, 6,500), (4, 6,000), and (26, 500).
Which statement describes the slope of the line?

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
