Water carried = 1/2 gallon
Water drank =
= 2/3 of 1/2 gallon
= 2/3 × 1/2
= 2/6
= 1/3 gallon
Find the invers of f(x)
f(x) = 2x - 6
y = 2x - 6
y + 6 = 2x
2x = y + 6
x = (y + 6)/2
f⁻¹(x) = (x + 6)/2
Solve f⁻¹(x) for x = 2
Subtitute x with 2
f⁻¹(x) = (x + 6)/2
f⁻¹(x) = (2 + 6)/2
f⁻¹(x) = 8/2
f⁻¹(x) = 4
The answer is 4
15/40 can be divided evenly by 5 to get, 5/8, which is the simplest form.
