1. 846 - 77
    769
    The answer is D.

2. f(t) = 3t² + 8
    f(4) = 3(4)² + 8
    f(4) = 3(16) + 8
    f(4) = 48 + 8
    f(4) = 56
   The answer is D.

3. The answer is B.

4. 2x + 12y - 24 = 0
     + 24 + 24
       2x + 12y = 24
    2x - 2x + 12y = 24 - 2x
   12y = 24 - 2x
   12y = -2x + 24
      12 12
       y = ⁻¹/₆x + 2
      f(x) = ⁻¹/₆x + 2
   The answer is C.

5. y = 4x - 8
   The answer is B.

6. 4x + 7y = 20
    4x - 4x + 7y = 20 - 4x
   7y = 20 - 4x
   7y = -4x + 20
      7 7
   y = ⁻⁴/₇ + 2⁶/₇
   The answer is C.
