Answer:
A
Step-by-step explanation:
The rule is, whenever you plug in g(x) into f(x) or vice versa, they always must equal x. So if you plugged in g(x) into f(x), then the outcome should be <em>x</em>. If the output is not x, then they are not inverses.
Answer: A≈440.44
Step-by-step explanation:
Using a linear function, it is found that the algebraic expression that shows the amount Ms. Jackson will pay for the small truck for the week is:
<h3>What is a linear function?</h3>
- A linear function is modeled by:
In which:
- a is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem:
- He pays an amount per mile, plus a flat weekly fee.
- Researching the problem on the internet, it is found that the weekly fee for the small truck is of $340, hence .
- For each mile, he pays $0.6, hence the slope is of .
Then, the expression is:

Step-by-step explanation:
Use Pythagoras' theorem
52² = 33.6² + x²
solve for x
