Question

if x and y in the direct variation if y is equal to 10 then x is equal to 5 . find the value of y when x is equal to 10 ? ​

Answer 1

Explanation:

y 10

X 5

then the constant variation will be 10-5=5

Answer 2

Answer:-

$\rm y=20$

Correct explanation:-

$\sf x proportional\:to\: y$

$\sf y=kx$

when $\sf x=5 , y=10$

$\sf 10=k(5)$

$\sf \dfrac{10}{5}=k$

$\sf k=2$

when $\sf x=10$

$\sf y=kx$

$\sf y=(2)(10)$

$\sf y=20$
