Question 24166: Assume that y waries inversely as x, and y=18 when x=3.Find the constant of variation.Then write an equation for the relation. Answer by venugopalramana(3286) (Show Source):
You can put this solution on YOUR website! y waries inversely as x...THIS MEANS Y=K/X WHERE K IS A CONSTANT
and y=18 when x=3.SUBSTITUTING IN ABOVE EQN.,WE GET ..18=K/3..OR..K=18*3=54
Find the constant of variation....=54
Then write an equation for the relation....Y=54/X
