How many solutions?One SolutionNo solutionInfinitely Many Solutions - 6. Multiple ChoiceSolve for x and y
3x + 2y = 16
7x + y = 19(-2,5)(-2,-5)(2,-5)(2,5) - 7. Multiple ChoiceSolve:
3x + 2y = 16
7x + y = 19(-2,5)(-2,-5)(2,-5)(2,5) - 8. Multiple ChoiceSolve for x and y
3x + 2y = 16
7x + y = 19(-2,5)(-2,-5)(2,-5)(2,5) - 9. Multiple ChoiceAlexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2 haircuts and 4 hair dyes takes 450 minutes. Which system of equations represents the situation?3x + 2y = 315
2x + 4y = 4503x + 2y = 450
2x + 4y = 3152x + 2y = 315
3x + 4y = 450 - 10. 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 - 11. Multiple ChoiceThe school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Which equations represents the system that could be used?1s + 3c = 38
2s + 3c = 523s + 1c = 38
3s + 2c = 52s + c = 38
s + c = 523s + 3c = 38
1s + 2c = 52 - 12. Multiple ChoiceLast season two running backs on the Steelers football team rushed a combined total of 1550 yards. One rushed 4 times as many yards as the other. Let x and y represent the number of yards each individual player rushed. Which system of equations could be used?x + y = 1550
y = 4xx + y = 1550
y = x + 4y - x = 1550
y = 4xy = 1550 + x
y = x + 4 - 13. Multiple ChoiceLisa and Tammy are selling items at the craft show. Which might be a reasonable solution from the graph showing the number of items sold when they both have earned the same amount?(1, 12)(3, 19)(5, 25)(0, 10)

- 24. Multiple ChoiceWrite two linear equations that model data shown in the table.57m+ s = -135
14m + s = 40357m - s = - 135
14m + s = 41757m + s = 135
14m - s = 16757m + s = 192
14m + s = 167 - 25. Multiple ChoiceWhich of the following is not a solution to this system of inequalities?(0,-1)(0,3)(4,0)(6,-2)
