If f(7)=22, then f-1(22)=

nignag [31]

Answer:

$f^{-1}$ (22) = 7

Step-by-step explanation:

The inverse function maps the output of the function back to its input

f(7) = 22 means when input is 7 the output is 22

The inverse maps the output 22 back to the input 7 , that is

$f^{-1}$ (22) = 7

Triangle ABC has angle measures as shown. What is the value of X? Show your calculations.

dezoksy [38]

180-96= 84
That means 8x+12=84
84-12=72
That means 8x=72
72÷8=9
therefore X=9
