x a y and constant of variation is 1 by 2. find y when x=6​

Answer 1

To Find :

The value of y , when the value of x is 6

Given :

$\tt{ \bull \: x \: \alpha \: y}$

$\tt{ \bull \: x \: = 6}$

$\tt{ \bull \: constant \: of \: proportionality \: is \: \frac{1}{2} }$

We know that :

if a quantity is directly proportional to the other, then .

$\tt{ if \: x \: \alpha \: y}$

$\tt{ then \: x = ky}$

where, k is constant of proportionality .

Solution :

Given, x = 6

constant or k = 1/2

so, the value of y :

$\tt {x = ky}$

$\tt{ \implies \: 6 = \frac{1}{2} y}$

$\implies \tt{y = 6 \times 2}$

$\red{ \underline{ \boxed{ \tt{ \therefore \: y = 12}}}}$

Hence, y = 12

Answer 2

Answer:

Step-by-step explanation:

constant or k = 1/2

so, the value of y :
Hence, y = 12
