Answer:
the answer to 315 / 3 is 105
Distance from start to look out point is calculated below
d1 = 8 3/4 miles - 0 miles = 8 3/4
Distance from look out point to giant boulder is,
d2 = 8 3/4 miles - 4 1/4 miles = 9/2 miles = 4.5 miles
Thus, the answer is equal to 4 1/2 miles. The answer is letter C.
F(x) = 4x - 9
let f(x) = y, this implies that x = f⁻¹(y)
y = 4x - 9 Let us solve for x.
4x - 9 = y
4x = y + 9
x = (y + 9)/4
Recall that x = f⁻¹(y),
x = (y + 9)/4
f⁻¹(y) = (y + 9)/4
That means that for f⁻¹(x)
f⁻¹(x) = (x + 9)/4
Hope this explains it.
