    Answer:

    60feets

    Step-by-step explanation:

    The question is incomplete. The complete question is “Let y = safe load in pounds and x = length in feet of a horizontal beam. A constant of proportionality k exists such that y = k/x. If a beam can hold 2,000 pounds at 15 feet, what maximum length should be used to safely support 500 pounds”

    Since y = k/x

    k = xy

    If a beam can hold 2,000 pounds at 15 feet, x = 15ft y = 2000pounds

    K = 15×2000

    k = 30,000

    To get the maximum length that should be used to safely support 500 pounds, we will use the relationship k = xy where y = 500pounds, k = 30000

    x = k/y

    x = 30000/500

    x = 60feets

    The maximum length that should be used to safely support 500 pounds is 60feets
