OpenStudy (dobby1):

are you there?

OpenStudy (anonymous):

yes i am here @Dobby1 sorry its so late

OpenStudy (dobby1):

ok so this is pretty easy I am going to do this with you and teach you as we go okay?

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

iv got a few more after this one can you help with those too?

OpenStudy (dobby1):

so the first thing that we do since this is a absolute value problem we have to get rid of the absolute value sign and we will see depends on what kind of question because I dont know how to do all questions and i have to go get allergy shots soon

OpenStudy (anonymous):

ok works for me

OpenStudy (dobby1):

but back to the question to get rid of the absolute value sign we make our equation look like this -4≤ a – 9 ≤ 4

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

btw the answers could be a – 9 ≥ 4 and a – 9 ≤ –4 a – 9 ≤ 4 or a – 9 ≥ –4 a – 9 ≥ 4 and a – 9 ≤ –4 a – 9 ≤ 4 and a – 9 ≥ –4

OpenStudy (dobby1):

ok they dont want to simplify got it then the answer would be the last one

OpenStudy (anonymous):
