Answer:

Step-by-step explanation:
Consider the real number y such that f ⁻¹(x) = y

We need to find y in order to determine the expression of f ⁻¹(x)
f(y) = x ⇔ -2y + 4 = x
⇔ 4 - x = 2y
⇔ y = (4 - x)/2

there are 5 solutions. Or 4
Answer: more than likely 20-30 feet because it would be eaiser to calculate the distane you are than how long it would take to get there
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
Find two points on the line
(2,0) and (4,1)
The slope is given by
m= (y2-y1)/(x2-x1)
=(1-0)/(4-2)
= 1/2
