Write an equation of the parabola shown.

Step-by-step explanation:

General equation of a parabola parallel to the x-axis: (y - k)^2 = 4p(x - h).

Vertex = (h, k) = (0, 0)

Directrix: x = h - p = -2.

Since h and k are 0, p must be 2.

Therefore the equation is y^2 = 8x.

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.
