Review of Systems of Equations

Pick the ordered pair that is NOT a solution

• (0,0)

• (1,-1)

• (2,0)

• (4,-4)

^{What is the solution?} 

• 1

• -2

• (1, 2)

• (1, -1)

Choose the best description for this system (Hint:  Both lines are graphed over each other)

• infinitely many

  Inconsistent

• infinitely many

  consistent and independent

• Infinitely Many Solutions

  consistent and dependent

-4x - 6y = 6
4x + 6y = -4

• no solution

• (2,0)

• (-4,0)

• (0,0)

Does the system have one, none or infinite solutions?
8x + 4y = 12
y = -2x + 3

• (0,3)

• (3,0)

• No solution(parallel lines)

• Infinitely many solutions

The talent show committee sold a total of 530 tickets in advance. Student tickets cost $3 each and the adult tickets cost $4 each. If the total receipts were $1740, which system could be used to find how many of each type of ticket were sold?

• S + A = 530
  3S + 4A = 1740

• S + A = 530
  4S + 3A = 1740

• S + A = 1740
  3S + 4A = 530

• S + A = 1740
  4S + 3A = 530

Solve for x and y.

y = 2/3x - 2

x + y = 3

• (0,3)

• (0,-3)

• (3,0)

• (-3,0)
