Question

If x and y vary inversely y=45 then find x when constant of variation =9.​

Answer 1

Answer:

Hi,

definition :

INVERSE PROPORTION:

Two quantities x and y are said to vary in inverse proportion if

xy = k---------(1)

where k is a constant.

according to our problem

y = 45,

k = 9.

put these values in (1),

xy = k

X x 45 = 9

x = 9/45

x = 1/5

I hope this will help for you

if y = 45 then x = 1/5
