- 1. Multiple ChoiceSolve for x and y
3x + 2y = 16
7x + y = 19(-2,5)(-2,-5)(2,-5)(2,5) - 2. Multiple ChoiceSolve for x and y
y = 2x + 1
y = 4x - 1(1,3)(-1,-3)(-1,3)(3,1) - 3. Multiple ChoiceThe equations of two lines are:
2x-y=4 and y=-2x+8.
What is the value of x in the solution for this system?x=8x=3x=11x=5 - 4. Multiple ChoiceChristian had brochures printed for a new business venture. Christian originally ordered 4 boxes of black-and-white brochures and 3 boxes of color brochures, which cost a total of $134. After those ran out, Christian spent $120 on 3 boxes of black-and-white brochures and 3 boxes of color brochures. Which system represents this situation?x+y=134
x+y=1203x+3y=134
4x+3y=1204x+3y=134
3x+3y=1207xy=134
6xy=120 - 5. Multiple ChoiceTwo brothers went shopping at a back-to-school sale where all shirts and shorts were the same price. The younger brother spent $175 on 7 new shirts and 7 pairs of shorts. The older brother purchased 6 new shirts and 7 pairs of shorts and paid a total of $165. How much did one shirt cost?$5$10$15$20
- 6. Multiple ChoiceIf a system of equations has no solution, what does the graph look like?intersecting linesparallel linesskew linesintersecting lines
- 7. Multiple ChoiceWhat is the value of the y-coordinate of the solution to the system of equations
x-2y=1
x+4y=71-134 - 8. Multiple ChoiceWhat is the solution?(1, -1)(-1, 1)(0, -2)(2, 0)
- 9. 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 - 10. Multiple ChoiceWhat is the solution?One SolutionNo solutionInfinitely Many Solutions
