A concession stand at a baseball game sells hot dogs and boxes of popcorn, Justin buys a total of 9 snacks. The number of popcorn boxes he buys is three less than twice as many hot dogs. Which system of equations models this situation if he bought h hot dogs and p boxes
of popcorn?
O A. h = 3 - 2p
p=9- h
OB. h=2p - 3
h+p=9
O c. p=3 – 2h
h = 9-p
• D. p = 2h - 3
h+p=9

When x = 3 and y = 5, by how much does the value of 3x2 – 2y exceed the value of 2x2 – 3y ?

What is the slope of the line shown below?

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.
