Answer:
7x+9
Step-by-step explanation:
f(x)=7x-5
g(x)=x+2
f[g(x)]= Substitute g(x) in for x in the function f(x)
=7(g(x))-5
= 7( x+2) - 5
Distribute
= 7x+14 - 5
Combine like terms
=7x +9
Answer:
7m + 5
Step-by-step explanation:
1) Simplify.
(12m + 1) - 1 (5m - 4) -> (12m + 1) - 5m + 4
2) Eliminate unnecessary parenthesis.
(12m + 1) - 5m + 4 -> 12m + 1 - 5m + 4.
3) Combine like terms.
12m - 5m = 7m, 4 + 1 =5 -> 7m + 5
The solution is 7m + 5
Given that t<span>he
manager of Theatre A says that they usually go through about 15 cups of
popcorn kernels and about 5 cups of oil each weeknight.
Then, the ratio </span><span>value of oil to popcorn kernels for theatre A is 5 / 15 = 1 / 5.
Given that t</span><span>he manager of Theatre B says that they order 18 cups of oil and 72 cups of popcorn kernels each week.
Then, the </span>ratio value of oil to popcorn kernels for theatre B is 18 / 72 = 1 / 4.
Given that t<span>he manager of Theatre C says that their concessions use 6 cups of oil and 32 cups of popcorn kernels on a busy Saturday.
Then, the </span>ratio value of oil to popcorn kernels for theatre C is 6 / 32 = 3 / 16.
