What is the average rate of change from x= 0 to x=5?

a. -80
b. -40
c. -8
d. -2

-8.

Step-by-step explanation:

That would be change in height  divided by change in time:

= (40 - 80) / (5 - 0)

= -40 / 5

= -8.

answer: c

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
