Answer:
D. 31
Step-by-step explanation:
First Plug 2 into f(x) and solve.
You should get 22.
Then plug f(2) which is equal to 22 into g(x).
So, plug 22 into g(x).
You should get 31.
Answer:
5
Step-by-step explanation:
The question ask for G[H(1)] so we have to find the H(1) first and it doesn't ask for anything about the F(x) so we don't have to worry about it. I dont know if H(x) = x*2 or x^2 but i'll consider it as x^2.
H(1) = (1)^2 <u>Plug in 1 for x</u>
H(1) = 1
since we find H(1) = 1 we just put it as G(1) because its same as G[H(1)]
G(1) = 3x + 2
G(1) = 3(1) +2 =5
G(1) = G[H(1)] = 5
Do you need the number 9/2 simplified? if so, the answer is 4 1/2 :) hope this helps!
15 people, each want 2 hamburgers, so there will be 15*2 = 30 hamburgers.
However, we only want the plain hamburgers.
3 people want hamburgers with cheese: 30-3 = 27 plain hamburgers
2 people want hamburgers with mustard: 27-2 = 25 plain hamburgers
2 people want hamburgers with catsup: 25-2 = 23 plain hamburgers
Jim and his dad will make 23 plain hamburgers.
Hope this helps!! Let me know if you have ANY questions.
