#83 you can double click on the photo, please

OpenStudy (unklerhaukus):

mistake

OpenStudy (anonymous):

wasn't i supposed to distribute inside the brackets first?

OpenStudy (anonymous):

oh then 3 x 4 ?

OpenStudy (dumbcow):

3[4-(x+4)] 3[4-x-4] 12 -3x -12

OpenStudy (unklerhaukus):

\[-5x+15≥3[4-(x+4)]\] \[-5x+15≥3[4-x-4]\] \[-5x+15≥12-3x-12\] \[-5x+15≥-3x\]

OpenStudy (anonymous):

then what? i have to express my solution using set-builder and interval notion, so do I factor or simplify more?

OpenStudy (anonymous):

like by getting my X's combined?

OpenStudy (unklerhaukus):

\[-5x+15≥-3x\] \[15≥2x\] \[7.5≥x\]

OpenStudy (anonymous):

the back of the book, where the answers are says xIx \[\le \] 15/2

OpenStudy (anonymous):

that looks confusing sorry, im new

OpenStudy (unklerhaukus):

|dw:1328247390545:dw| good cause 15/2 =7.5
