Question 1149872: Is about inequalities, I know the rule of flipping the sign if you multiply or divide by a negative numbers but a few examples confuse me.
To make this inequality 5x+2y<14 into the slope-intercept form y=mx+b, please tell me if the sign has to be flipped.
I do it like this
5x+2y<14
y<-5/2x+14/2
y<-5/2x+7
I am not dividing by a negative number but 5 is negative, 2 is positive, should I flip the sign or not?

Question 1150721: How do I simplify |pi-2| to not have the absolute value signs?
The answer that I got was {pi-2 if pi-2 is greater than or equal to 2/pi and -pi+2 if -pi+2 is less than 2/pi.
I can't tell if I'm wrong or putting it in wrong. I'm taking an online winter course and don't know how to type the answer in.
Thank You!

Question 1150767: I was taking a practice test and got the following question wrong:
Solve the following inequality:
-12x -3 > 45
1. x = -8
2. x = -5.3
3. x = -4
4. x = -3.5
The correct answer is "x = -8." However, I selected number 2 (x = -5.3).
Both answers, when multiplied by -12 is greater than 45. Why is #2 wrong?
