I am not sure how many of you are familiar with the rules when you are dividing an inequality by a negative number...you must switch the signs...like I said more confusing than difficult.
Here is a link to a site that explains it pretty well

You will need this information to do question 12 part c...yes the answer in the book is correct.
If it is still unclear I will go over it tomorrow in class, briefly, as we have lots of circle stuff to do...but this will be on the test so make sure you remind me!
