Chapter 8.5, Problem 1PE

(a)

To determine

To fill: The blanks provided in the statement “let $k$ be a nonzero constant. If $y$ varies directly as $x$, then $y=\underset{\_}{}$, where, $k$ is the constant of variation”

(b)

To determine

To fill: The blanks provided in the statement “let $k$ be a nonzero constant. If $y$ varies inversely as $x$, then $y=\underset{\_}{}$, where, $k$ is the constant of variation”

(c)

To determine

To fill: The blanks provided in the statement “let $k$ be a nonzero constant. If $y$ varies jointly as $x$ and $w$, then $y=\underset{\_}{}$, where, $k$ is the constant of variation”
