I have a few questions on inequalities below:
Question 1. Would someone be able to provide an example of the difference between "and" vs "or" inequalities?
Question 2. I also have a question on this specific problem below...
X^2 ≥ 9
Would it be incorrect to express the answer as follows?
3 ≤ x ≤ -3
Normally, I see the greater number on the right-hand side in this form.
Question 3.
For combining inequalities, Manhattan Prep mentioned that you can add inequalities together as long as the signs are facing the same way. But, do you cannot combine a less than sign with a less than or equal sign (and vice versa for combining a greater than sign and a greater than equal to sign), correct? You can only pair less than with less than and then greater than with greater than?
Thank you for your help
