Answer 4

It's to trick you. Sometimes they do that on tests. We can only have one right answer so right away we know it can't be A or D

Answer 5

oh ok

Answer 6

x - 1 < -12

Lets get x by itself. To do that we have to add 1 to both sides in order to get rid of that -1 ...what do we get then?

Answer 7

x < -11 ?

Answer 8

Right that means that in a number line -11 will have an open circle right?
