I know the answers are x>-4 and x>4 I just don't know how to write it in interval notation

OpenStudy (lucaz):

both inequalities says x is greater than some value, then you have to consider wich one is the greatest value

OpenStudy (anonymous):

so its (4,inf)?

OpenStudy (lucaz):

yes, when x is greater than 4 it works for both inequalities

OpenStudy (anonymous):

ok, I understand. I always get confused on these problems but I appreciate your help!

OpenStudy (lucaz):

no problem
