Transcript

00:03

Okay A c t Math people were aspiring Get the

00:06

right answer here A number line graph is shown right

00:09

there This pretty thing took us hours to draw which

00:12

inequality corresponds to the number line graph shown All right

00:19

Identity crisis alert The variable acts just can't decide who

00:23

he wants to be today What We're all about experimentation

00:26

But his indecisiveness isn't making our lives any easier Luckily

00:30

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

a minor detail there So the answer is a and

01:17

that's it We can't think of anything clever to say
