Respuesta :
Given is = x and y vary inversely ; this means when x increases y decreases and when y increases x decreases but the product remains unchanged.
It can be written as = [tex]x=\frac{1}{y}[/tex]
Now, the given values are :
x = 2 and y = 7
So, the correct answer is option B.
[tex]y=\frac{14}{x}[/tex] or x*y=14
Hence, option B is correct.
