Trish is ordering t-shirts from a website that charges a certain amount per t-shirt plus a flat rate for shipping. The cost for a given number of t-shirts is shown in the table. 20a. Write an equation to represent the situation. (Write your answer with no spaces, all lowercase letters, and write the slope as a decimal)

20b. What does the slope mean in the context of the situation?

20c. What does the y-intercept mean in the context of the situation?

Solve -2(4y + 6) = 52. 5 -5 8 -8 and !

The graph of y=x3 is transformed as shown in the graph below. which equation represents the transformed function?

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.
