It can only go up to x = 1.5 so the second point does NOT fall in the interval. It's only the first point of (-1.6, 56)
Answer:
Step-by-step explanation:
let x = how many joe sold
let 4x = how many abe sold
900 = x + 4x
900 = 5x
180 = x
joe sold 180
and abe sold 4x
4(180) = 720
hat means Abe sold 720 trucks
finally, let's check our answer to make sure the total is 900
180 + 720 = 900
our answer is right
Answer:
9x² + 28x - 32
Step-by-step explanation:
Given
(9x - 8)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
9x(x + 4) - 8(x + 4) ← distribute both parenthesis
= 9x² + 36x - 8x - 32 ← collect like terms
= 9x² + 28x - 32
