Question

direct and Inverse proportion observe the following table and find if x and y are directly proportional​

Answer 1

Answer:

a. x=20,y=40

on forming equation

we get x=2y

now on checking others values by this equation

............

all values satisfied xproportinal to y

note that only equatuon x= someconstant × y are

implies rgat x is proportinal to y if you form equation like

x=3y+2. then it is not necessary that x is proportional to y

similary on checking b and c

we cound that x is not proportinal to y
