Hi guys. this is free points for the one who does not have points. please don't report it im just trying to help. so please don't report it.

What's the difference between: x≥0 and nonnegative integer. ?

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

Solve the equation below: (x+4)/6x=1/x a. x=2 b. x=0,2 c. x=-2 d. x=0,-2
