number lines allow us to represent all the abstract possibilities
- 00:33
for the rial number that x could be well this
- 00:37
graph shows ah highlighted region between negative eight and three
- 00:40
So Acts must be between negative 8 and three and
- 00:43
pretty much all the answer choices give you that Since
- 00:46
the end points of the highlighted segment are open circles
- 00:49
well than x must be greater than but not equal
- 00:53
to right esso In this case it must be greater
- 00:56
than but not equal to negative aid and less than
- 00:59
but not equal teo three right there Got it So
- 01:03
the right answer is a because they can't be equal
- 01:06
to any of these And all the other potential answers
- 01:08
have like the equal sign anything there somewhere in the
- 01:10
question other than e which forgot about acts which is
- 01:13
