Question

When y =20, x =5 find the constant of variation

Answer 1

Answer:

the answer is as follows:

Step-by-step explanation:

Given proportion is x∝y

⇒x=ky  (where k is a constant of variation)

⇒k=  

y

x

​

      ....(1)

Substituting x=20 and y=5 in equation (1), we get

k=  

5

20

​

=4

∴ constant of variation (k)=4.
