Answer:

AC = 24

DE = 18

Step-by-step explanation:

Assume that the given figure is a parallelogram. One of the properties of a parallelogram is that the diagonals bisect. This means that the following statements are true:

2 ( CE ) = AC

Substitute,

2 ( 12) = AC

24 = AC

(BD) / 2 = DE

Substitute,

(36)/2 = DE

18 = DE

Explain why the graph below does not represent a direct variation. a. the line does not intercept the x-axis c. the line does no
Rama09 [41]

The graph is not a direct variation because the line does not go through the origin; option C.

<h3>What is a direct variation?</h3>

A direct variation is a relationship between two or more quantities in which as one quantity increases, the other quantity also increases. Similarly, if the other quantity decreases, the other decreases as well.

For the graph of a direct variation, the line must pass through the origin.

Therefore, the graph does not represent a direct variation because the line does not go through the origin.

In conclusion, direct variation involves a corresponding increase or decrease in two related quantities.
