Question

If y varies inversely with x and y = 3 when x = 4, what is the value of y when x = 2?

Answer 1

\(\huge\color{blue}{ \bf y=\frac{k}{x} }\) is the inverse variation form.

Answer 2

A. \[y=\frac{ 1 }{ 6 }\]
B. y=2
C. y=6
D. y=12

Answer 3

@SolomonZelman Thanks you

Answer 4

these are the options, as I can see....

\(\Large\color{red}{ \bf y=\frac{k}{x} }\) plugging in 4 for x and 3 for y,

\(\Large\color{red}{ \bf 3=\frac{k}{4} }\) multiply both sides by 4, and k=12.


NOW, ....
when x=2, y=?

\(\Large\color{red}{ \bf ?=\frac{12}{2} }\)
