Use the equations \(y=\frac{1}{x}\) and \(y=\frac{1}{x+3}\). Use a graphing calculator or computer to graph both equations.
You start 5 kilometers from the finish line and walk \(1 \frac{1}{2}\) kilometers per hour for 2 hours, where \(d\) is your distance from the finish line. Graph the situation.
They can be used to estimate the average number of hours \(h\) per week that a household in the United States watches television programs. In all three models, \(t\) is the number of years since \(1985 .\) Hours spent watching television: \(h=0.57 t+54.85\) Hours spent watching talk shows: \(\quad h=0.35 t+4.06\) Hours spent watching game shows: \(h=-0.2 t+3.4\) According to the model, in what year will a household watch an average of 10 hours of talk shows per week?
Solve the equation if possible. $$ 4 x+8=24 $$
Write the equation in slope-intercept form. Then graph the equation. $$ 4 y+12=0 $$
