Use the following information. Your school drama club is putting on a play next month. By selling tickets for the play, the club hopes to raise \(\$ 600\) for the drama fund for new costumes, scripts, and scenery for future plays. Let \(x\) represent the number of adult tickets they sell at \(\$ 8\) each, and let \(y\) represent the number of student tickets they sell at \(\$ 5\) each. Graph the linear function \(8 x+5 y=600\)
Use the equations \(y=\frac{1}{x}\) and \(y=\frac{1}{x+3}\). Use a graphing calculator or computer to graph both equations.
