y 10
X 5
then the constant variation will be 10-5=5
Verified answer
Answer:-
[tex]\rm y=20[/tex]
Correct explanation:-
[tex]\sf x proportional\:to\: y[/tex]
[tex]\sf y=kx[/tex]
when [tex]\sf x=5 , y=10[/tex]
[tex]\sf 10=k(5)[/tex]
[tex]\sf \dfrac{10}{5}=k[/tex]
[tex]\sf k=2[/tex]
when [tex]\sf x=10[/tex]
[tex]\sf y=kx[/tex]
[tex]\sf y=(2)(10)[/tex]
[tex]\sf y=20[/tex]
