Answers

  1. Answer:

    B

    Step-by-step explanation:

    y = k/(x + 3)

    Let x = 2

    Let y = 8

    k = ?

    8 = k/(2 + 3)      Combine the terms on the right

    8 = k/(5)            Multiply both sides by 5

    8*5 = k

    k = 40

    Let x = 7

    y = 40/(7 + 3)

    y = 40/10

    y = 4
