I really new help with this question. I can't figure any of these out.

If an x intercept only touches the x axis it means it has a multiplicity of 2. if an intercept goes through the axis it has a multiplicity of 1 true false

1. a parachutist is 800 feet above the ground when she opens her parachute. she then falls at a constant rate of 5 feet per second. select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5 i need

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10
