Question

If two quantities x and y are related to each other in such a way that xy is constant, then x and y are said to be in:​

Answer 1

Answer:

inverse proportion

Step-by-step explanation:

xy=k

x=k/y

which is inverse proportion

Answer 2

Answer:

"x" and "y" are said to be inversely proportional to each other.

Step-by-step explanation:

Given that, "x" and "y" are two quantities.

And also the product of x and y is constant (k)

i.e. x × y = k.....(1) (let)

We can write equation (1) as follows :

   x =k/y

⇒ x ∝ 1/y (When the two quantities are related by some constant, then the proportionality symbol is introduced by removing the constant).

i.e. "x" is inversely related to "y".

It means that when the value of "x" gets increased by twice, then the value of "y" gets halved, and vice versa.

Therefore, "x" and "y" are said to be inversely proportional to each other.
