Ivahew [28]3 years ago
3 0

Answer:

The correct option is b.

Step-by-step explanation:

It is given that y varies directly as x.

y\propto x

y=kx

It is given that y is 6 when x is 72.

6=k\times 72

Divide both sides by 72.

\frac{1}{12}=k

The constant of proportionality is \frac{1}{12}.

k=\frac{y}{x}

\frac{1}{12}=\frac{y}{8}

\frac{1}{12}\times 8=y

\frac{2}{3}=y

The value of y is \frac{2}{3}. The correct option is b.
