Answer:

C

Step-by-step explanation:

If you multiply the top equation by 2 and the bottom equation by -5, then there will be a 10x in the first equation and a -10x in the second, which you can cancel out in the next step. Therefore, the correct answer choice is C. Hope this helps!

What is the answer?....
Anon25 [30]

Answer:

third answer choice:  11

Step-by-step explanation:

f(x) = 4x + 3.  Now if we let x = 2, we get f(2) = 4(2) + 3 = 11.

This '11' becomes the input to function g:

g(x) = x - 2, so g(11) = 11 - 2, or 9.

Thus, g(f(x)) = 9
