Astro:

What is the problem saying?

Arieonna:

whch choice is the correct graph of /x/>4?

Astro:

exactly so what exactly is that asking us to find?

Arieonna:

the correct graph?

Astro:

nevermind, so which graph do you think we can eliminate first?

Arieonna:

maybe C

Astro:

Why do you think so?

Arieonna:

um well it does not make sence as a answer to me

Astro:

I know we can eliminate A,B, and E right away because they are closed circles, and we know its not great than or equal to.

Astro:

Do you think so?

Arieonna:

yes

Astro:

So that leaves us with C,D, and F

Arieonna:

ok

Astro:

Lets now test D

Astro:

If we input a number that is on the number line on D in for X is the equation true?

Astro:

Say we put |0|>4

Astro:

Is this true?

Arieonna:

um no 4 is not less than 0 is is a bigger number so it would be greater than

Astro:

Exactly, great job. We are now only left with two

Astro:

Let's test C

Astro:

If we take a number that is on the shaded area on the number line, would the equation be true? We can test this by |-5|>4

Arieonna:

no -5 is a small number so 4 is greater than -5

Astro:

Remember the absolute value rules, Absolute value always make a number positive |-a|= a |-2|= 2

Astro:

Does that make sense?

Arieonna:

a little

Astro:

So when we have a number in between the absolute value bars, it will always be positive

Arieonna:

ok so C would most likely be the answer

Astro:

Yes!

Astro:

I'm glad you followed along. Let me know if you need more help!
