What is the result of substituting for y in the bottom equation?

The square pyramid has a volume of 441 cubic inches. what is the value of x? 1/7x is the height x is the base

Amodel rocket is launched from a roof into a large field. the path of the rocket can be modeled by the equation y = -0.04x^2 + 8.6x + 4.8, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. how far horizontally from its starting point will the rocket land? a. 0.56 m b. 215.56 m c. 431.11 m d. 215.74 m

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5
