Question

Identify the variation as direct, inverse, joint or combined.

v = cw

A) direct
B) inverse
C) joint
D) combined

Answer 1

A.) Direct

Hope this helps.

Answer 2

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form
`y/x=k` or
`y=kx`

In this problem we have

`v=cw`

Let

v-----> the dependent variable

w-----> the independent variable

c-----> the constant of proportionality

therefore

`v=cw` -----> is a linear equation that represent a direct variation

the answer is the option A

Direct
