Identify as a direct variation, inverse variation or neither. y = 6x
2 answers:
Answer:
y=6x is a direct variation.
Step-by-step explanation:
In direct variation the relation between two variable is direct. It means y varies directly as x.
Where, k is constant of proportionality.
In inverse variation the relation between two variable is inversely proportional. It means y varies inversely as x.
Where, k is constant of proportionality.
The given function is
It is direct variation because y varies directly as x and constant of proportionality is 6.
Therefore, y=6x is a direct variation.

For this case what you should see is that you have two similar triangles.
We then have the following relationship:
((AB) / (BX)) = ((CD) / (DX))
We cleared CD:
CD = ((AB) / (BX)) * (DX)
Substituting the values:
CD = ((12) / (5)) * (2.5)
CD = 6
Answer:
CD = 6
