If y varies inversely with x and y triples, then what happens to x?
Accepted Solution
A:
Answer:The value of x is reduced to one third when the value of y is tripled.Step-by-step explanation:Here, y varies inversely with x.⇒[tex]y \propto \frac{1}{x} \\\implies y = \frac{k}{x}[/tex]Here, k = Constant of Proportionality.⇒ k = x y .......... (1)Now, given y' = 3 yto find the value of x'Putting the value in [tex]y ' = \frac{k}{x'} \implies 3y= \frac{k}{x'}\\\implies k = 3yx'[/tex]or, k = 3 y x '.......... (2)From above statement (1) and (2)⇒ xy = 3yx'or, x ' = x/3Hence, the value of x is reduced to one - third when the value of y is tripled.
