Jim decided to go for a drive in his car. He started out at 0 miles per hour (mph). He then

accelerated 20 mph down his street. Then, to get on the highway he accelerated another 35 miles

per hour. A car was going slow in front of him so he slowed down 11 mph. He then got off the

highway, so he slowed down another 7 mph. At what speed is he driving?

4 Miles per hour.

Step-by-step explanation:

Since he slowed down to 11 MPH at the slow car, We cab then use that as a baseline. They turned off the highway and slowed another 7 MPH, so we just subtract 7 from 11 to get 4 MPH.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
