Decide if each pair of expressions is EQUIVALENT or NOT EQUIVALENT. Drag each pair of expressions from the left to the correct category on the right.
6(-4t + 5) and -2(15 - 12t)
1/5 (20t−15) and 4t - 34t−3
1.5−2t and 0.25(8 - 6t)
−3(t−7+5t+8) and -18t-3

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.
