I need helpppp!!!

anonymous · Answer

subtract 4 from both sides and then create 2 equations,  |2x | > 8 and  |2x| < 8.

anonymous · Answer

then i simplify that right?

welshfella · Answer

the 2x + 4 can be negative or positive so we have

2x + 4 >8      and   2x + 4 <  - 8

solve both inequalities

anonymous · Answer

the second one needs to be negative as well, but to graph you need to use open circles and it will be an    or statement    i believe

anonymous · Answer

what do u mean by the second one has to be negative?

welshfella · Answer

@MoOse   your method is incorrect

anonymous · Answer

do the signs change when i solve the second equation? @welshfella

welshfella · Answer

No 
in both equation you subtract 4 form both sides and then divide both sides by 2

welshfella · Answer

the inequality sign only changes when you divide by a negative

anonymous · Answer

to graph would it be open circle or closed circle?

welshfella · Answer

open
