Answer 15

question, is this for an online test?

Answer 16

Yeah , I've already taken it , I'm just making sure I'm right before I submit it . because I'm not really good with math . I'm only sending the ones I'm not 100% sure on . It's a 50 Question test & there's only 7 more I'm not sure about .

Answer 17

ok but that is still cheating just so you know...as a test you cant get help before submitting
if you submit it first then check answers thats ok, then you will know how you did

Answer 18

Oh .. Well I've been right .. It's till cheating ?

Answer 19

haha no i havnt helped you yet have i :)

anyway, for just checking answers use "wolframalpha.com" but use it responsibly
so far your method for solving these inequalities is correct so i wouldn't worry too much on the rest of your questions

Answer 20

Alright .. Well . Thank you . I don't cheat .. My mom can tell when I'm lying . I'm honest when it comes to academic integrity . I cheated once a long time ago & I got into a lot of trouble .. So I'm not doing that again .
