q + 12 – 2(q – 22) > 0 = <56???

OpenStudy (phi):

looks like you got the correct answer: q + 12 – 2(q – 22) > 0 distribute the -2: q + 12 -2q + 44 > 0 collect terms: -q +56 > 0 add q to both sides: 56 > q which is the same as q<56 or if you like, subtract 56 from both sides: -q > -56 negate both sides (multiply by -1) *and* flip the relation q < 56

OpenStudy (mertsj):

\[q+12-2q+44>0\] \[-q+56>0\] \[-q>-56\] \[q<56\]

Directrix (directrix):

I concur: q < 56
