okay so what do you think

Answer 2

are you there

Answer 3

I'm not too sure, could you explain please? @Daniel56k

Answer 4

okay

Answer 5

do you know segment addition postulate

Answer 6

sorry i don't understand what you just explained

Answer 7

dc=ab+ef

Answer 8

meaning you have \[\frac{ (-x+5)+(-x-9) }{ 2 }\]

Answer 9

can you try and finish it up

Answer 10

I got -x - 2.
Would that make the answer y = -x - 2?

Answer 11

yep
