Hello!
To find the answer, we know how much she runs in a minute. We need to find the hour. There are 60 minutes in an hour, so we multiply.0.09 by 60.
She was running 5.4 mph.
There is an app to tell you the answer
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).

A's area is 4x3=12, B=2x3=6, so yes, A is twice the area of B
a Answer: YES
b Answer: One side doubled, the other stayed the same, so area doubled.
