If ∠AOB, ∠BOC, and ∠COD are supplementary angles, then what is the value of x and m∠COD?

Which rational number could be graphed between -4 and -5

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

When y’all answer can y’all explain too !
