1 hour = 60 minutes
60 ÷ 2 = 30
30 × 15 = 450
Answer = 450 miles in 1 hour
Hope this helped :)

Answer:</h3>
- d. The y-intercept is 1 space higher.
- a. 9 to the power of -1/2
<h3>
Step-by-step explanation:</h3>
1. Changing f(x) to f(x) + 1 adds 1 to every output value of the function, moving that value "1 space higher". This is true for the y-intercept, too.

2. The rules of exponents apply:
- a^b · a^c = a^(b+c)
- 1/a^b = a^-b
You apparently want to simplify ...
... 9^(1/4) × 9^(1/2) / 9^(5/4)
... = 9^(1/4 + 1/2 - 5/4)
... = 9^((1+2-5)/4)
... = 9^(-2/4) = 9^(-1/2)
