Solve the equations 1 2 mv2 + 1 2 Iω2 = mgh and v = rω for the speed v using substitution, given that I = mr2 and h = 4.20 m. (Note that mass m and radius r will both cancel, so their numerical values aren't required.)

Math
I have been asked to solve the following system of linear inequalities by graphing. I tried replacing with various numbers but even though the they work in the equations my graphs change from consistent to inconsistent. Please help.
