Question

Given the following endpoints (A & B) and midpoint (M) on a number line, find the coordinates for A & B.
M(-11)
A(2x + 3)
B(5x + 3)

Answer 1

m-a = m+b

-a = b

Answer 2

?

Answer 3

yeah, thats what i was thinking too lol

Answer 4

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

Answer 5

when m = 0 we got a = b then

Answer 6

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

0 = 3x

x = 0

Answer 7

-11 +3 = -8

-11 - 3 = -14

Answer 8

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

Answer 9

that's isnt an answer choice

Answer 10

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
