Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation. If y varies inversely with x, and for y = 1, x = 3, find y when x = 9

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
