PLEASE HELP ME... Jeanine Baker makes floral arrangements. She has 10 different cut flowers and plans to use 6 of them. How many different selections of the 6 flowers are possible?

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
