Write a system of equations to model each situation. Then, identify a solution. On Sunday, Bonnie ran a 20-mile race in 2.3 hours. The route for the race goes over hills, and she knows she can run 8 minutes per mile uphill and 6.5 minutes per mile downhill. How long did she spend running uphill and downhill?

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
