Measure the length of AC. Use coordinate algebra to locate a point E on ACsuch that the ratio of AE to EC is equal to the ratio of AD to De. Shon how you derived your answer. (Hint Letx and AC -x represent the two line segnents that make up AC.)

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.
