100 points! Describe a situation in which the rate of change for data over a short period of time would be a good estimate for the rate of change over a longer period of time.

Write 2 - 4 sentences describing this situation and the patterns you would expect to find in the data.

Include your reasoning on why this situation is a good indicator for the rate of change over a longer period of time.

Write 2 - 4 sentences describing a factor that might impact the rate of change so that it is no longer a good indicator of the rate of change in future observations.

Include your predictions about the effects of the factor on the rate of change.

answer: 2530

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
