How to solve for x, y, and z in the system of equations? 2x+4y-z=9
-3x+y+z=14
5x+2y+z=-6

What is the average rate of change for this function for the interval from x=2 to x=4 ?

What is the shape of the height and weight distribution

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
