Answer 1

please see analysis

step by step explanation

`if \: y \: varies \: inversely \: as \: \: as \: x \ \: meanc \\ y = (k)/(x) \\ where \: y = 1 \: \: x = 3 \\ 1 = (k)/(3) \\ k = 3 * 1 = 3 \\ equation \: connecting \: x \: and \: y \\ y = (3)/(x) \\ finding \: y \: when \: x = 9 \\ y = (3)/(9) \\ y = (1)/(3)`
