Problema Solution

Given T to be the midpoint of Line AB with AT = 3/4x + 6 and TB = 1/2x + 9. Fin AB

Answer provided by our tutors

Since T is the midpoint, AT=TB and AB=2AT=2AB=AT+AB. Therefore, we can set the equations equal to each other.

3/4x+6=1/2x+9


using Algebrator to solve for 'x', we get:

x=12


Now we can find either AT or TB:

AT=3/4x+6

AT=(3/4)12+6

AT=8+6

AT=14


Now we can find AB:

AB=2AT=2(14)=28
