Last week len spent $18 to bowl 4 games. this week he spent $27 to bowl 6 games. len owns his bowling ball and shoes, so he only has to pay for each game that he bowls. if each of these bowling games cost the same amount of money, what is the constant of proportionality between the money spent and the number of games played?

a. 1.5
b. 2.0
c. 4.5
d. 9.0

Determine if the equation defines y as a function of x: 2xy = 1. yes o no

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.

Ineed the solution to this problem and the steps.
