The U.S. Bureau of Labor Statistics projects job growth by using three models to make low, moderate, and high estimates. The equations below model the projected number of auto mechanics \(m\) from 1994 to \(2005.\) In all three models, \(t\) is the number of years since 1994 Model 1: m=13,272 t+736,000\( Model 2: m=9455 t+736,000\) Model 3: m=11,455 t+736,000\( a. For each model, write an equation that enables you to predict the year in which the number of auto mechanics will reach \)800,000\(. b. In the same coordinate plane, graph the related function for each equation that you found in part (a). According to each model, in what year will the number of auto mechanics reach \)800,000 ?$ c. Visual THINKING Which model gives a high estimate of the number of mechanics? a low estimate? How can you tell this from the graphs of the models?
MARATHON In Exercises \(64-66,\) you are running in a marathon. You either run 8 miles per hour or walk 4 miles per hour. Write an equation to show the relationship between time run and time walked during the 26.2 -mile course.
Find the x-intercept and the y-intercept of the graph of the equation. $$y=\frac{1}{3} x-\frac{7}{3}$$
Write the equation in slope-intercept form. Then graph the equation. $$ x+2 y-6=0 $$
