Nolan is buying a season pass to a performing arts center. - One performing art center charges $100 for the pass, plus $15.00 to park each visit. - Another performing arts center charges $75 for the pass, plus $20.00 to park each visit. How many times would Nolan need to visit the two performing arts centers for the cost to be the same?

Sarah has been keeping track of how many hours she practices basketball each week and thinks that the percentage of free throws she makes during practice improves the more she practices. To check this, she makes a graph comparing the number of hours she practices each week with the percentage of free throws she makes each week. Based on what she learned in her Algebra class, she realizes that her graph represents a function. Which of these could be Sarah’s graph?

• A

• B

• C

• D

Function 1 and function 2 can be represented as shown.

Which statement correctly compares the rates of change of functions 1 and 2?

• The slope of function 1 is -3, and the slope of function 2 is 2, so function 2 is changing at a faster rate.

• The slope of function 1 is 2, and the slope of function 2 is 3, so function 2 is changing at a faster rate.

• The slope of function 1 is -3, and the slope of function 2 is -2, so function 1 is changing at a faster rate.

• The slope of function 1 is -2, and the slope of function 2 is -3, so function 1 is changing at a faster rate.
