A storm moves at a rate of 8 miles per hour. It is 200 miles away from Freeport and headed directly for this town. The equation y = 200 – 8x represents this function. What does the slope and y-intercept represent in this scenario?

Answers

Pls see answer below.

Step-by-step explanation:

In this case, our slope is -8. This means that every hour, the storm is getting closer to the town by 8 miles per hour.

Our y-intercept is 200, which means that its' initial position is 200 miles away from the town.

Ben can type 153 words in 3 minutes. At this rate, how many words can he type in 10 minutes.

Answers

Answer:

In 10 minutes, he could type 510 words

Step-by-step explanation:

153/3=51 51 words a minute   51 times 10=510

Answer:

510 words

Step-by-step explanation:

This is how I would solve this problem:

153 words = 3 minutes

153/3 = 3/3

51 words per minute

To find the number of words Ben can tye in 10 minutes, we need to multiply the unit rate (51:1) by 10. Like so:

51 words * 10 = 1 minute * 10

510 words = 10 minutes

This means that Ben can types 510 words in 10 minutes.
