GH(Line) bisects CF(Line), CF= 2Y-2 and CD 3Y-11. Find the length of CD, The CD is the half segment of CF. ANd i can't figure it out. Also, If Y is between X and Z, then X,Y, and Z are colllinear, is that always true, sometimes true, or false?

If you're needing immediate on-demand answers, you'll need to contract with a paid service which offers such. Sorry. :roll:

If |CD| = (1/2)|CF|, then |CF| = 2|CD|. Plug the given expressions into the stated relation, and then solve the resulting linear equation for the value of Y.

Review the definitions of "between" and "collinear". These should answer your question. :wink:
