Solve the following equation for x:
6x + 2 = 8x - 2

• x = -1
• x = 1
• x = 2
• x = 10/14

Solve the following equation for x:
3x + 8 = 8 + 3x

• x = 3
• x = 8
• infinite solutions
• x = 0

Solve the following equation for x:
10x + 2x + 5 = 8x + 4x + 7

• no solution
• infinite solutions
• x = 12
• x = 0

For the equation below to have one solution, which value cannot go in the blank:
___ + 12 = 8x + 4

• 8x
• 4x
• 0
• 9x

5x - y = 16

• -y = 5x + 16
• y = 5x + 16
• x = 5y - 16
• y = 5x - 16

Solve -2 = 4r + s for s.

• s = -2 + 4r
• s = 2 - 4r
• s = -2 - 4r
• s = 2 + 4r

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

For the function f(x) = -3x + 3 find f(0).

• 0
• -3
• 3
• -1

Which set of values is a function?

• (9,5) (10,5) (9,-5) (10,-5)
• (3,4) (4,-3) (7,4) (3, 8)
• (6,-5) (7, -3) (8, -1) (9, 1)
• (2, -2) (5, 9) (5, -7) (1, 4)

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D: {1, -3, -4,}
  R: {0, 1, 2, -4}
• D:{0, 1, 2, -4}
  R:{1, -3, -4}
• D:{0, 1, 2, 3, 4}
  R:{1, -3, -4}
