Question

4 y is directly proportional to
(x+y) andy= 32.4 when n=4
calculate the value
when 169.
100
y = ,​

Answer 1

Step-by-step explanation:

By definition of proportionality,

If y is directly proportional to x,

y α x

∴y=Kx .......Equation 1

where K is constant of proprtionality

Now,

Given that x=2,y=4

putting the above values in Equation 1 we get,

4=K×2

∴K=2

Answer 2

the answer is 2.....
