Solve the inequality. Express the answer using interval notation. |x − 1| > 1
This is exactly the same as the last one you 'did'.
Oh wait, no it's not. this is greater, not less.. Sorry. \[|a| > b \iff a > b \text{ or } a < -b \]
polpak i am checking my answers please quit trying to reteach me everything
If you are 'checking your answer' it would save time to put your answer and we could tell you if it's right.
you have to solve two inequalities: \[x-1>1\] or \[x-1<-1\] solve them separately and get two intervals
Also, there's wolframalpha.com which is quite good for checking your answers.
wolfram doesnt help in this case. is the answer 2 and -2
Wolfram does help, but no that's not the answer.
It breaks up into two inequalities you have to solve separately: x - 1 > 1 and x - 1 < -1
doesn't help me and i got (−, −2] ∪ [2, )
infinity symbol after first negative and after 2
i dont know why it erased
x - 1 > 1 + 1 +1 --------- x > 2 AND x - 1 < -1 + 1 + 1 --------- x < 0
thats not the answer
(−oo, 0) ∪ (2,oo )
That looks correct yes.
