Question

if x is directly proportional to 1/yand x = 4 when y =2 what is the value of x when y=0.4?​

Answer 1

Answer:

Directly proportional: as one amount increases, another amount increases at the same rate.

Step-by-step explanation:

hope it helps u

Answer 2

Step-by-step explanation:

now 1/y = 1/2 when y = 2

so z/x = z/ 4 when x = 4

so x is direct propotional to 1/y then val. of z =

z/4 = 1/2

z = 2

now if z = 2

and y = 0.4 then val. of x

z/x = 1/y ( as x is directly proportional to 1/y)

2/x = 1/ 0.4

0.8 = x answer.
