Assume that y varies inversely with x. If y=9 when x=7, find y when x=2. Enter in any fractions using a / (e. g. "1/2" is the same as 12 and 1 1/2 is the same as 112).

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares
