  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.
