9) The segment bisector is the ray that is dividing XY into XM and MY, which is MN. The segment XY is equal to the sum of each section:
[tex] (3x+1)+(8x-24)\\ 11x-23 [/tex]
10) The segment bisector is the line dividing XY into XM and MY, which is line n. The segment XY is equal to the sum of XM and MY:
[tex] (5x+8)+(9x+12)\\ 14x+20 [/tex]
