The vertex of this parabola is at (-5,4). Which of the following could be it’s equation?

The answer is D.

Step-by-step explanation:

If the parabola is -5 down the x axis, (x+5)^2 will be included in the equation.

Since it is also moved 4 units up the y axis, +4 will be the second coordinate.

D

Step-by-step explanation:

if you substitute the number -5 as x into the equation, you should get 4 for y.

If any of the equations fit, that would be the answer

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.

the answer is a.

135 and 80
