m-a = m+b

-a = b

?

amistre64 · Answer

yeah, thats what i was thinking too lol

amistre64 · Answer

the distance from m to a is equal to m to b

amistre64 · Answer

when m = 0 we got a = b then

amistre64 · Answer

2x+3 = 5x+3 ....maybe

0 = 3x

x = 0

amistre64 · Answer

-11 +3 = -8

-11 - 3 = -14

amistre64 · Answer

it makes better sense to me now :)  i really shouldnt doubt myself like that in front of my other personalities.  sends a bad message :)

that's isnt an answer choice

anonymous · Answer

okay, all you have to do is these:
First, the point 2x+3 and 5x+3 has a midpoint of -11.

(2x+3+5x+3)/2=-11
(2x+3+5x+3)=-22
7x+6=-22
7x=-22-6
7x=-28
x=-4

A=2x+3
=2(-4)+3
=-8+3
=-5

B=5x+3
=5(-4)+3
=-20+3
=-17
