Step-by-step explanation:
I think because wouldn't you take the 0.085 · 100
(get mad if I'm wrong i might be)
9^2 + 12^2 = 225. the square root of 225 is 15. x=15
Step-by-step explanation:
given f(x) = 2/x and g(x) = 2/x
f(g(x)) = 2/(g(x)) = 2/2/x = x/2 × 2 = x
g(f(x)) = 2/(f(x)) = 2/2/x = x/2 × 2 = x
therefore they are inverses
since f(g(x)) = g(f(x)) = x.
