its something you have to know, it doesnt have to be given

remember that | | these 2 lines mean absolute value, so if its negative you take it to bne positive, and if its positive you leave it to be positive

@dan815 ohh then idk . im completely dumb when ut comes to math ...

do you know what the graph of y=x looks like
anonymous
  • anonymous
@dan815 yes
dan815
  • dan815
okay so |X| is very similiar but you take all the negative part and make that positive

now you take the negative part and make it positive for |X|

now |X-2| is this V shape moved 2 units to the right

now we simplfied our equation earlier with |x-2|+10-10=12-10 |x-2|=2 so we want to see where our value is 2 on the graph

0 and 2 does that make sense
dan815
  • dan815
maybe a much simpler way to go about that is |x-2|=2 now you know that if you get a -2 in the abs value it will be 2 and 2 in the abs value is 2 so we have to solve x-2=-2 and x-2=2 these 2 equations
