Row 1, Col 1
How many solutions does the system have?
y=2x + 5y = 2x - 7
What is none?
1,2
Solve for x.x=2yz=7y
3x + 5y – z = 13
What is 6.5?
1,3
Solve for y.y² + x² = 34y² - x² = 16
What is 5 and -5?
1,4
If x varies inversely as y, and y=6when x=12, what is the value of x when
y = 9?
What is 8?
2,1
Solve the system:2x + 3y = 28
3x – y = 9
What is (5,6)?
2,2
Solve for y.x + y + z = 15x – y – z = -5-x – y + z = -1
What is 3?
2,3
Is (-3,4) a solution of the system?x² + y² = 25y = -2x - 2
What is yes?
2,4
Find the vertices ofxy = 25
What are (5,5) and (-5, -5)?
3,1
Charles has 125 coins, all dimes and quarters.If he added 10 quarters and 12 dimes, the
value of the coins would be $24.45. Write a system of equations to represent this
situation.
d + q = 125
25q + 10d = 2075
3,2
Solve for z.x + 2y – 3z = 3
3x – 4y + 6z = 4y – 2z = 2
What is -3?
3,3
Find the points of intersection of:y = x²
x² - y² = -2
Ask Mrs. Carrigan!
3,4
Complete the table to show thaty varies inversely as x.
What are (-4,-12), (6,8), (-2,-24), (1,48)?
X 3 -4 -2 1
y 16 8
4,1
The sum of Bill’s age and his father’sage is 64. In 5 years, Bill’s father’s age
will be 10 less than 3 times Bill’s age then.How old is each person now?
What are 16 and 48?
4,2
Graph the solution set.y ≤ x + 3
y > (x – 1)² - 5
Put solution on board.
4,3
Solve. x² + y² = 362x² - y² = 12
Ask Mrs. Carrigan!
4,4
Graph xy = 10
Put answer on board.
5,1
Pop and Zeb have gone fishing in their smallmotorboat. They traveled 19.5 miles
downstream in 3 hours. After 3 hours on the way back upstream, they have only gone8.7 miles. Find the speed of the current.
What is 1.8 mph?
5,2
Find the vertices of the region defined by:
x ≥ 0y ≥ 2x – 2.5y ≤ 0.5x + 2
What are (0, -2.5), (3, 3.5), (0, 2)?
5,3
Solve.2/(x+1) + 5/(y-1) = 125/(x+1) + 2/(y-1) = 9
What is (0, 3/2)
5,4
The sum of the squares of two numbers is88. The difference of the squares of the two
numbers is 10. What might the two numbersbe?
