Answer:

c = - \frac{16}{3}

Step-by-step explanation:

Given

6.5c - 2.5c + 9 = - 7 ← combine like terms on left side

3c + 9 = - 7 ( subtract 9 from both sides )

3c = - 16 ( divide both sides by 3 )

c = - \frac{16}{3}

F(x)=x^2-5 and g(x)=3x+1 then f(g(2))
LuckyWell [14K]

Answer:

f(g(2)) = 44

Step-by-step explanation:

g(2) = 3(2) + 1 = 7

Plug 7 into f(x) since g(2) = 7

f(7) = 7² - 5 = 44

f(g(2)) = 44
