Steve took a 300 mile business trip and decided to travel by car. He drove the speed limit for half the trip until an accident occurred and he had to stop for a few hours in traffic. Stove then decided to drive slower than the speed limit the rest of the way to be safe. This situation models which type of function?

He traveled for 2.5 hrs at 54 mi/hr

He traveled for 3 hrs at 61 mi/hr

answer: .75 km

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.
