Answer:
Proofs
Step-by-step explanation:





They are not inverse because f^-1(x) = x - 3/2 is not the inverse to g(x) = 2x - 3.
First, we have
s1/r1 = s2/r2
The question also states the fact that
s/2πr = θ/360°
Rearranging the second equation, we have
s/r = 2πθ/360°
Then we substitute it to the first equation
s1/r1 = 2πθ1/360°
s2/r2 = 2πθ2/360°
which is now
2πθ1/360° = 2πθ2/360°
By equating both sides, 2π and 360° will be cancelled, therefore leaving
θ1 = θ2
Subtract 3y and move it to the right
X= 1 - 3Y
