In the equation x ( y + 4 ) = 1 , y is Options: A . &nbspDirectly proportional to x B . &nbspNot proportional to x C . &nbspInversely proportional to x D . &nbspCan't say

Answer: Option B : B Expanding the given equation, we get x y + 4 x = 1 Here, x y = 1 − 4 x , whichis not a constant . Similarly, x y = ( 1 4 y − x 4 ) , whichis not a constant . So, y is notproportional to x .

In the equation x(y+4)=1, y is

Question

In the equation x (y + 4) = 1, y is

Options:

A . Directly proportional to x

B . Not proportional to x

C . Inversely proportional to x

D . Can't say

Answer: Option B
:
B
Expanding the given equation, we get

x y + 4 x = 1

Here, x y = 1 - 4 x, whichis not a constant

. Similarly,

\frac{x}{y} = (\frac{1}{4 y} - \frac{x}{4}), whichis not a constant

So, y is notproportional to x .
