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
