A bridge support is represented by the top half of an ellipse, shown in the figure to the right. The point Q, which is the center of the ellipse, is at the origin. The bridge support is 18 feet high at its center and it is 25 feet from either end of the bridge to the center. Find the equation that best describes the ellipse.

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

27 +27 or 27times 2=54

the diffrence is 0

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
