How many solutions would a system of linear equations have if the equations are parallel and different y-intercepts?
Zero Solutions
Shoot. Score.
100 Points for each basket made
r + s = -6
r - s = -10
x = 4y
2x + 3y = 22
Ms. Carey bought 2 new shirts and a dress for $45. She then went back and bought another shirt and 4 dresses for $70.
Write a systems of equations for the situation.
2x + y =45
x + 4y = 70
How many solutions would a system of linear equations have if the equations are parallel and have the same y-intercept?
Infinite Solutions
y = 3x - 2
y = -x - 2
Work it out!
Each person from your team that does 10 push ups or 20 jumping jacks get these points.
y = x - 2
3x - y = 16
Mr. Daniels went to Dunkin and bought one coffee and a bagel, her total was $7. Ms. Flood went to Dunkin and bought 2 coffees and 3 bagels and spent $18.
Write a systems of equations for this situation.
x + y = 7
2x + 3y = 18
Is there 1 solution, No solution, or Infinite solutions for the following question?
3x - y = 19
-3x + y = 10
No Solutions
y - 3x = 3
y = 3x - 2
2x + 3y = 6
3x + 5y = 15

300 Points for each member of your team that comes up and does a 30 second dance!
What do you call your friends in THIS math class?
ALGEBROS!!! :D
How many solutions does the system have?
3y + 4x = 6
12y + 16x = 24
Infinite Solutions
y = (1/3)x - 3
2x - y = 8
2a - 4b = 12
-8a + 16b = -48
3s - 2t = 4
t = 2s - 1
Adult tickets for the school musical sold for $3.50 and student tickets sold for $2.50. On a given night, 321 tickets were sold for $937.50. How many of each kind of ticket were sold?
(135, 186)
adults-135
Children- 186
How many solutions does the system have?
-6y + 2 = -4x
y - 2 = x
One Solution
(1,3)
y = -3
x = 5
(1/3)x + (1/4)y = 10
(1/3)x - (1/2)y = 4
t + u = 12
t = (1/3)u
A shopper bought 6 shirts and 8 hats for $700. A week later, at the same prices, he bought 9 shirts and 6 hats for $660. What was the cost of one shirt?
What is $30?
