A road construction company is building a highway that is going to include a tunnel that cuts through a mountain. The company overlays their map over a coordinate plane in order to precisely calculate the locations of the entrance and exit of the tunnel. When graphed out, the highway follows the path of h(x)=1/3x and the mountain lies exactly along the function of m(x)=-|x-500|+300. If the highway starts at the origin, what are the coordinates for the entrance and the exit for the tunnel that will have to be drilled through the mountain?

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.

b and c

step-by-step explanation:

cause it equals more
