Compare the graph of car a to the table of car b to determine which car is traveling at the greatest speed and by how much.
a) car a is going 2 times faster than car b
b) car a is going 3 times faster than car b
c) car b is going 2 times faster than car a
d) car b is going 3 times faster than car a

C

Step-by-step explanation:

Because if Car A is going 7.5 miles and Car B is going 15 miles then Car B is going 2 times faster than Car A

7.5 x 2 = 15

step-by-step explanation:

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.
