A truck driver travels from a distributor to a retailer every week. The driver records the distance that he is from the retailer at dilferent times during his trip. After several weeks of collecting data, the driver creates a scatter plot of the data. The best-fit line is y = 73.6 --
67.8x, where x is the number of hours spent driving and y is the distance, in miles, from the retailer.
Which of the following statements are true? Select all that apply.
The distance from the retailer decreases with time.
The distance from the retailer increases with time.

The distributor is 73.6 miles away from the retailer
The distributor is 678 miles away from the retailer
The truck is traveling at a rate of 67.8 miles per hour.

B. The distance from the retailer decreases with time, D. The distributor is 73.6 miles away from the retailer, E. The truck is traveling at a rate of 67.8 miles per hour.

Answers: B, D, E.    

Step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
