Your number is 57.
Because....
47 + 10 = 57
67 - 10 = 57
Hope that helps!
Answer:
B. F(x) =X-4/11
Step-by-step explanation:
We are given the inverse function;
f^(-1)(x) = x + 4/11
Thus means, x was replaced with y and vise versa. Thus;
x = y + 4/11
Lets make y the subject;
y = x - 4/11
Thus,in inverse of a function we replace y with f(x) for the original function or f^(1)(x) for the inverse.
Thus, putting f(x) for y gives;
f(x) = x - 4/11
ABC=50
DCE=65
DEF= I think 115
I hope that helps I would appreciate brainliest if possible :)
