Solve each system of equations by elimination for real values of \(x\) and \(y .\) See Example 4 $$ \left\\{\begin{array}{l} x^{2}+y^{2}=13 \\ x^{2}-y^{2}=5 \end{array}\right. $$
Archery. See the illustration below. An arrow shot from the base of a hill follows the parabolic path \(y=-\frac{1}{6} x^{2}+2 x,\) with distances measured in meters. The inclined hill has a slope of \(\frac{1}{3}\) and can therefore be modeled by the equation \(y=\frac{1}{3} x\). Find the coordinates of the point of impact of the arrow and then its distance from the archer. (GRAPH CANNOT COPY)
Solve each system. See Using Your Calculator: Solving Systems of Equations. $$ \left\\{\begin{array}{l} x^{2}-y^{2}=-5 \\ 3 x^{2}+2 y^{2}=30 \end{array}\right. $$
Solve each equation. $$ \log 3 x=\log 9 $$
Solve each system of equations for real values of \(x\) and \(y.\) $$ \left\\{\begin{array}{l} y=x^{2}-4 \\ x^{2}-y^{2}=-16 \end{array}\right. $$
