Y varies inversely with x. When x = 3 then y = 5. Write a function to represent this relationship.

Mariulka [41]

Answer:

<em>The function to represent this relationship will be: $y= \frac{15}{x}$ </em>

Step-by-step explanation:

$y$ varies inversely with $x$ . That means......

$y= \frac{k}{x}..............................(1)$

where $k$ is a proportional constant.

Given that, when $x=3$ , then $y=5$

Plugging these values into the above equation, we will get.....

$5=\frac{k}{3}\\ \\ 5(3)=\frac{k}{3}(3)\\ \\ 15=k$

Now plugging this $k=15$ into equation (1).....

$y= \frac{15}{x}$

So, the function to represent this relationship will be: $y= \frac{15}{x}$
