Week 12 -precalc

This week in math we learned how to determine the points of intersection of a linear absolute value equation, for example

:|2x-3|=9

the first is to split the equation into separate ones. one of them you have to replace the absolute value signs with brackets then place a negative in front that has to be distributed followed by solving as shown below.

-(2x-3)=9

-2x+3=9

-2x=6

x=-3

The second step is to just remove the absolute value signs from the equation then solve

2x-3=9

2x=12

x=6

you can now determine that for the two points of intersection x would equal x=-3 and x=6
