What is the inverse function of f(x)=-1/4x +5 Select all that apply A: f1^1(x)=-x/5+4
B: f1^1(x)=-4(x-5)
C: f1^1(x)=-4x-5
D: f1^1(x)= -4x+20

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
