Question

If x = 15 and y = 1/30, then x
and y are:
A. Directly proportional
B. Inversely proportional
C. Neither directly nor inversely
proportional
D. Cannot be determined​

Answer 1

Answer:

$x$ and $y$ are inversely proportional and hence option b is correct.

Step-by-step explanation:

Given $x=15$ and $y=\frac{1}{30}$

Also we can write it as, $y=\frac{1}{2}\times\frac{1}{15}=\frac{1}{2x}$

So, as $x$ increases $y$ decreases and if $x$ decreases $y$ increases.

Hence, $x$ and $y$ are inversely proportional.
