To find the inverse, we need to solve for x in term of f(x)
f(x) = 5x + 4
5x + 4 = f(x)
Solve for x
5x + 4 = f(x)
5x = f(x) - 4
x =
x acts as the invers of f(x), and f(x) is the invers of x, so the inverse function will be
f⁻¹(x) =
Answer:
$30.62
Step-by-step explanation:
12% of 40 is 4.8
(10% is 4, 2% is 0.8)
40- 4.8= 35.2
13% of 35.2 is 4.576
(10% is 3.52, 3% is 1.056)
35.2- 4.576= 30.624
then rounded to 2 decimal places
30.62
4 doubled is 8. You can multiply 4*4*2 which equals 32.
