Answer:
A.
Step-by-step explanation:
To find the inverse of a function, first make f(x) a y
So,
y = -18
Then switch the x and the y
x = - 18
Solve, for y
It is 397.8 bc if u make 530.4 a fraction = 530.4/1 then u just multiply it by 3/4 u will get 1591.2/4 then u simply reduce it by dividing ( top in , bottom out ) and u get 397.8
Its C. i put my best guess into it even tho i kinda suck at geometry <span />
X + y while x = -23.5 and y = 14.7
-23.5 + 14.7
-8.8
5 is the answer you are looking for
