7. rent-a-car prince compact cars for a fixed amount per day plus a fixed amount for each mile driven. bientot rented a car for 6 days drove it 550 mi and spent $337. lisa rented the same car for 3 days drove 350 miles and spent $185 what is the charge per day in the charge per mile for the compact car?

9. solve the system of linear inequalities.
- 4x + 3y = 15
- 6x - 4y < 12

10. solve the system of inequalities (no. you may need to adjust your skill on the coordinate plane)

-7x+3y≤15
6x-5y< 12

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.
