Answer:

C) 2(4x² + 5x - 4) is your answer

Step-by-step explanation:

Factor out common factors from all terms.

Note the factors for 8 & 10:

8: 1, 2, 4, 8

10: 1, 2, 5, 10

2 is the largest common factor, and so factor out 2

8x² + 10x - 8 = 2(4x² + 5x - 4)

C) 2(4x² + 5x - 4) is your answer

Note that you cannot factor out anymore common factor numbers or variables.

Answer:

- 88

Step-by-step explanation:

$f(x ) = - 7 {x}^{2} + 8x - 8 \\ plug \: x = 4 \\ \\ \implies \: f(4 ) = - 7 {(4)}^{2} + 8(4) - 8 \\\\ \implies \: f(4 ) = - 7 \times 16 + 32 - 8 \\\\ \implies \: f(4 ) = - 112+ 32 - 8 \\ \\ \implies \: f(4 ) = - 120+ 32 \\\\ \implies \: f(4 ) = - 88 \\$

Find s(4) on the graph ! Please answer this !!!

erica [24]

s(4) This means that t = 4, so you can plug in 4 for "t" in the equation

s(t) = 9t - 4

s(4) = 9(4) - 4

s(4) = 36 - 4

s(4) = 32

(4 , 32) This is the point on the graph. To graph it, each unit/square can be 4 [so go by 4's]
