You and your friend leave your houses at the same time to meet at a restaurant. the distance (in miles) your friend is from the restaurant is given by y=−50x+75, where x is the number of hours since your friend left home. you live 90 miles from the restaurant and arrive at the same time as your friend. write a linear equation that represents your distance from the restaurant.

y=-40x+100 This equation says your friend lives 100 miles away and travels 40 miles per hour. He takes 2.5 hours to get there.

y = -40x + 100 If y=0 then x = 100/40 = 2.5 hours and if x=0 then y=100.

You are 150 miles away and it takes you 2.5 hours to get there so your equation is:

0 = -2.5v + 150 You are solving for velocity.

v = 150/2.5 = 60 miles per hour. Now we can write the answer to the problem.

y = -60x + 150 Compare that to the original statement.

y = -40x + 100 Your buddy's speed is 40 and yours is 60. He has 100 miles to go and you have 150. Otherwise it's the same equation.

Answer from: Quest

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
