The <em><u>correct answer</u></em> is:
The faster rate is when she hiked down 200 feet in 10 minutes.
Explanation:
The rate of change is given by the change in y over the change in x; in this case, the change in elevation over the change in time.
For the first part of the hike, the change in elevation was -200 and the change in time was 10; this gives us a rate of change of -200/10 = -20.
For the second part of the hike, the change in elevation was -300 and the change in time was 20; this gives us a rate of change of -300/20 = -15.
She hiked downhill faster during the first part of the hike, at 20 feet per minute.

I just used Calculator Soup, it helps me with problems that are extremely hard for me to do (look it up)
Answer:
Its a i just took the test
Step-by-step explanation:
First we solve for y₁
3×5 - 5y₁ = 20
15 - 5y₁ = 20
-5y₁ = 20 - 15
-5y₁ = 5
y₁ = -1
(5, -1)
Now we solve for x₂
3x₂ - 5×2 = 20
3x₂ - 10 = 20
3x₂ = 20 + 10
3x₂ = 30
x₂ = 10
(10, 2)
A) Increase. This is because the mean of the first two cars is smaller than the mean of all three cars.
b) Cannot be determined. Need more values.
c) Cannot be determined. Need more values.
