Question

math help please??

Answer 1

Let f(x) = -4x + 7 and g(x) = 10x - 6, find f(g(x)).

-40x + 24

-40x + 31

-40x + 64

-40x + 70

Answer 2

f(g(x)) is f(x) with g(x) plugged in as every x.

so f(g(x)) = -4(10x - 6) + 7

Answer 3

@Euler271 what do i do next?

Answer 4

expand.

-4(10x) + (-4)(-6) + 7 = 31 - 40x

Answer 5

would it be the 3rd one?

Answer 6

@Euler271

Answer 7

2nd one.

Answer 8

ohh okay thankyou! @Euler271 would you be wiling to help me with any more?

Answer 9

i guess. you just want answer?

Answer 10

if thats what you want to give me, im not very good at algebra 2. :c @Euler271

Answer 11
