7) a

8) a, c, d

9) it is incorrect because he did not distribute the three to both terms. The correct work would be 3(4x+12) = 180 ; 12x+36 = 180 ; 12x = 144 ; x = 12

If f(x) =1/x and g(x) = x - 2 what is f(g(x)) when X = 1

Answer:

f(g(x)) = -1

Step-by-step explanation:

$f(x) = \frac{1}{x} \\ \\ g(x) = x - 2 \\ \\ \implies \: f(g(x)) = \frac{1}{x - 2} \\ \\ \implies \: f(g(1)) = \frac{1}{1 - 2} \\ \\ \implies \: f(g(1)) = \frac{1}{ - 1} \\ \\ \implies \: f(g(1)) = - 1$
