I would appreciate the steps to the answer please...
Suppose that y varies inversely with x, and y = 6 when x = 8. What is an equation for the inverse variation?
• y = x/48
• y = 2x
• x = y/2
• y = 48/x

asked by Sandra
  1. xy=k is the inverse variance equation
    Since 8*6 = 48, we have

    xy = 48
    or
    y = 48/x
