Answer 4

A compound inequality would be \( a < x < b\)

Answer 5

So what will 'a' and 'b' be in this case?

Answer 6

a = -8? b = 8?

Answer 7

Not quite..it says GREATER than -8.. if you put -8 in the 'a' spot it gives you:

\(-8 < x < b\)

Which says that -8 is LESS THAN.

Answer 8

okay, so -8 would be b?

Answer 9

Yep, and 'a' will be?

Answer 10

but all of the possible answers have -8 first

Answer 11

Oh. Well can I see your choices?

Answer 12

Oh, I totally forgot that I didn't type them out already, oops. Yeah, here's the choices.

Answer 13

Wow, this is much easier than I thought..

\(<\) this is the less than sign.
\(>\) this is the greater than sign.

\(\le\) this is the less than or equal to sign.
\(\ge\) this is the greater than or equal to sign.

The sentence says GREATER THAN -8, but LESS THAN 8.

So which one should be your answer?

Answer 14

That's what's confusing me is that there isn't any greater than signs and -8 is at the beginning so

Answer 15

I feel like it's C

Answer 16

but I'm hesitant to believe anything that I think is right haha

Answer 17

Same..it doesn't say any 'or equal to' signs..and C is the only one that doesn't have any..

Answer 18

Lol.

Yeah, this question doesn't seem to make much sense to me.. :l

I think greater than -8, but less than 8 should look like:

8 < x < -8

But I guess C is your best choice.

Answer 19

Thank you, it was right.

Answer 20

Now this question is a beast and I'm scared lol.

Answer 21

Ugh, sorry. I can't help you here..I'm horrible with sequences.

Answer 22

hahaha that's okay thanks
