Find the value of the missing variable
21. y varies directly with x. If y = -4 when x = 2, find the constant of variation.
22. y varies inversely with x. If y = 40 when x = 16, find k.
23. y varies inversely with x. If y = 7 when x = -4, find y when x = 14.
24. y varies directly with x. If y = 105 when x = -5, find y when x = 1.6.
25. y varies directly with x. If y = 75 when x =25, find x when y = 25. (Round off to the nearest hundredths)
