anonymous · Answer

the answer should be c. you will set it up  as $$-7\le4x+1$$ and solve for x and do the same thing for the other side

anonymous · Answer

the otherside should look like $$4x+1\le5$$

anonymous · Answer

so which of the multiple choice answers is it?

anonymous · Answer

–7 ≤ 4x + 1 ≤ 5
-8≤4x≤4 subtract 1
-2≤x≤1 divide by 4
-2≤x and x≤1

after double checking some math it should be a not c
