C. 5

D. 12

1 answer

The length of CD¯¯¯¯¯¯¯¯ is 7 - (-9) = 16 units.

Let the length of CE¯¯¯¯¯¯¯¯ be x units. Since the ratio of CE to CD is 3/4, we have:

(x)/(16) = 3/4

To solve for x, we can cross multiply:

4(x) = 3(16)

4x = 48

x = 48/4

x = 12

Therefore, point E is 12 units from point C.

The answer is D. 12.
