Question 878983
{{{30>=-7x-12>16}}}



{{{30+12>=-7x-12+12>16+12}}} Add 12 to all sides



{{{42>=-7x+0>28}}}



{{{42>=-7x>28}}}



{{{42/(-7)<=-7x/(-7)<28/(-7)}}} Divide all sides by -7 (this will flip the inequality signs)



{{{-6<=1x/1<-4}}}



{{{-6<=x<-4}}}



-------------------------------------------------------



To graph {{{-6<=x<-4}}}



Step 1) Draw a number line



Step 2) Plot a closed circle at x = -6



Step 3) Plot an open circle at x = -4



Step 4) Shade between those circles.
