Please help!!! Due tomorrow!! Suppose x and y vary inversely, and x=-3 when y= 1/3. What is the value of y when x=9

OpenStudy (anonymous):

Since you know x and y vary inversely. You can say y=a/x where a is some constant. Now with the given values you can solve for a to determine what the relation between x and y is

Is it -1???

So you have a = -1? Now you know y=-1/x

OpenStudy (anonymous):
