- 1. Multiple ChoiceSolve for x and y
5x + 3y = 7
y = 4(4,1)(4,-1)(1,4)(-1,4) - 2. Multiple ChoiceSolve for x and y
2x − 3y = −1
y = x − 1(-2,-3)(0,-1)(3,4)(4,3) - 3. Multiple ChoiceSolve for x and y
3x + 2y = 16
7x + y = 19(-2,5)(-2,-5)(2,-5)(2,5) - 4. Multiple ChoiceSolve the system of equations.
y = 4x+1
3x + 2y = 13(1, 5)(5, 1)(0.25, 2)∅ - 5. Multiple ChoiceSolve the system given:

- 13. Multiple ChoiceA large pizza at Palanzio’s Pizzeria costs $6.80 plus $0.90 for each topping. The cost of a large cheese pizza at Guido’s Pizza is $7.30 plus $0.65 for each topping. Which system of equations could be used to find the number of toppings when both companies cost the same amount?y = 6.80 + .65x
y=7.30+.90xx + y = 6.80
x + y = 7.30y = 6.80+.90x
y = 7.30 + .65xy + .90x = 6.80
y + .65x = 7.30 - 14. Multiple ChoiceSome students want to order shirts with their school logo. One company charges $9.65 per shirt plus a setup fee of $43. Another company charges $8.40 per shirt plus a $58 fee. Which equation represents the number of shirts when both companies charge the same amount?y = 9.65 + x
y = 8.40 + xy = 9.65x + 43
y = 8.40x + 58y =9.65x
y = 8.40xy = 9.65x - 43
y = 8.40x - 58 - 15. Multiple ChoiceSteffen graphed two lines in order to find the solution to a given system of equations.
What is the solution?(-3,-8)(-8,-3)(3,-8)(8,3) - 16. Multiple ChoiceSolve:
8x + 4y = 12
y = -2x + 3(0,3)(3,0)No solution(parallel lines)Infinitely many solutions - 17. Multiple ChoiceDavid is running a concession stand at a soccer game. He sells nachos and sodas. Nachos cost $1.50 each and sodas cost $0.50 each. At the end of the game, David made a total of $78.50 and sold a total of 87 nachos and sodas combined. Which system of equations represents this situation?1.5x+0.5y=78.5
x+y=871.5x+0.5y=78.5
1.5x+0.5y=87x+y=78.5
1.5x+0.5y=87x+y=78.5
x+y=87 - 18. Multiple ChoiceCaitlin won a bag full of money! She has 49 bills in all. She counts $1,430. There are $20 dollar bills and $50 dollar bills. How many of each bill does Caitlin have?
WRITE a system where T= # of $20 and F = # of $50.T + F = 1430
20T + 50F = 49T+ F = 49
10T + 5F = 1430T + F = 49
20T + 50F = 1430T + F = 49
T + F = 1430 - Answer choicesTagsAnswer choicesTags
