The sales tax is $4.32 -4.00 = $0.32.
The tax rate is
.. $0.32/$4.00 = 0.08 = 8%
The equivalent to 3/4 is 6/8.
The inverse is y = x/2 - 4
Steps involved are -
- replace f(x) with y: y = 2(x + 4)
- Then switch y and x: x = 2(y + 4)
- Finally make y the subject:
- x = 2(y + 4)
- x/2 = y + 4 (divide by 2)
- x/2 - 4 = y (subtract 4)
- So, the inverse is y = x/2 - 4
<h3>What is the formula for inverse function?</h3>
- In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f.
- The inverse of f exists if and only if f is bijective.
- f-1(y) = y/2 = x, is the inverse of f(x).

Angle one equals 85 because when an angle is a complement of another angle that means their degrees added together equal to 90 degrees. And so you just do 90-5=85 to get your answer.
