Question 119440: Find the solution set in interval notation: x+12/x+2 <= 3
Thank you so much!!! :D
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! (x+12)/(x+2)-3 <= 0
----------------
Find the values x cannot take:
x=-2
------------------
Draw a number line; x=-2
Find a test point in each interval to find the solution set:
If x=-3, (-3+12)/(-3+2)-3<-0, true
If x=-1, (-1+12)/(-1+2)-3<=0, false
--------------
Solution: (-inf,-2)
======================
Cheers,
