Get started for freeSCHOOL BAKE SALE You have one hour to make cookies for your =school bake sale. You spend 20 minutes mixing the dough. It then takes 12 minutes to bake each tray of cookies. If you bake one tray at a time, which model can you use to find how many trays you can bake? (Review 3.3 and 3.6) A. \(x(20+12)=60\) B. \(12 x+20=60\)
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?
Plot and label the points \(R(2,4), S(0,-1), T(3,6),\) and \(U(-1,-2)\) in a coordinate plane.
Find the slope of the graph of the linear function \(f\). $$ f(9)=-1, f(-1)=2 $$
LOGICAL REASONING In Exercises \(56-59\), tell whether the statement is true or false. Justify your answer. The \(x\) -intercept of the graph of \(3 x+5 y=30\) is 10
