Use inspection to describe each inequality's solution set. Do not solve any of the inequalities. $$(x-2)^{2}>0$$
Use the four-step procedure for solving variation problems given on page 424 to solve. \(y\) varies jointly as \(m\) and the square of \(n\) and inversely as \(p\) \(y=15\) when \(m=2, n=1,\) and \(p=6 .\) Find \(y\) when \(m=3, n=4,\) and \(p=10\).
Solve each inequality using a graphing utility. $$ 2 x^{2}+5 x-3 \leq 0 $$
Use inspection to describe each inequality's solution set. Do not solve any of the inequalities. $$\frac{1}{(x-2)^{2}}>0$$
Write an equation that expresses each relationship. Then solve the equation for \(y .\) \(x\) varies jointly as \(z\) and the difference between \(y\) and \(w\).
