Answer
Part 1) f(x)⁻¹ = 40 - x/2,500
Part 2) quantity
Explanation
f(x)= 100,000-2,500x
In finding the inverse of F(x) we make x the suject of the formula.
f(x)= 100,000-2,500x
2,500x = 100,000 - f(x)
x = 100,000/2,500 - f(x)/2500
x = 40 - f(x)/2,500
Now interchange x with f(x).
f(x)⁻¹ = 40 - x/2,500
Answer:
5 yards = 15 feet = 180 inches
Step-by-step explanation:
180 inches plus 18 inches = 198 inches
198 x 3 = 594 inches
594 inches = 49 feet 6 inches = 16 yards 1 foot 6 inches, or 16 yards 18 inches
