it is given that y is directly proportional to x.
what is the constant of variation?

Part a : solve - vp + 40 < 65 for v . part b : solve 7w - 3r = 15 for r show your work!

What is the solution to the equation in the & show work i’m very

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.
