Answers
#c <= 14# Graphed on a number line:
Explanation:
Method 1:
Remember multiplication or division of an inequality by a negative reverses the inequality.Dividing both sides of
#-6c >=-224# by#(-16)#
gives#c <= 14# ~~~~~~~~~~~~~~
Method 2:
Add#16c+224# to both sides
giving#224 <= 16c#
then divide both sides by#16#
to get#14 <= c#
