Asystem of equations has 1 solution.if 4x-y=5 is one of the equations , which could be the other equation ?

Find cot x if sin x cot x csc x = √2

The change in water level of a lake is modeled by a polynomial function, w(x). described how to find the x-intercepts of w(x) and how to construct a rough graph of w(x) so that the parks department can predict when there will be no chage in the water level. you may create a sample polynomial of degree 3 or higher to use in your explanations.
