    The second one is C. you plug in the first number for x and the second number for y. its saying 19 = 4 (4) + 3. and 19 = 16 + 3 is 19 = 19 so C is the answer.

    What is the simplified form of the expression 7[63: (5^2-2^2) - 1]?

    7[63: (5^2-2^2) - 1]

    = 7[63: (25-4) - 1]

    = 7[63: (21) - 1]

    = 7[3-1]

    = 7 (2)

    = 14

    answer is C. 14

    Which is a solution of the equation y=4x+3?

    answer is

    C. (4,19)

    y=4x + 3

    19 = 4 (4) + 3

    19 = 16 + 3

    19 = 19
