We can form this algebraic equation to work the equation out:
16 + 2x = -24
2x = -40
x - 20
Hope I helped.
Answer:
Slope = 
Step-by-step explanation:
F(g(x)) where you see an 'x' in f(x) put a g:
f(g(x)) = 1/(g-7), now step by step: g - 7 = 6/x+7-7=6/x, and 1/(g-7)=1/(6/x)=x/6!
I let the second one for you. Sorry if you disagree!
