Find x-intercept and y-intercept of line: 5x+8y=-14

5x+8y=-14

8y = -5x - 14

y = -5/8 x - 14/8

y-intercept when x = 0 so y = -14/8 = -7/4

x-intercept when y = 0 so

-5/8 x - 14/8 = 0

-5/8 x = 14/8

x = 14/8 * (-8/5)

x = -14/5

y-intercept (0 , -7/4)

x-intercept (-14/5 , 0)

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
