How do you solve this?

Question

n-10 > or equal to 0 or -5+n < -6

On my paper is says:
Solve each compound inequality and graph this solution.
I have a line but i dont know how i should line it up...
so how do i solve this problem?

Answer 1

just treat the > and < like equals signs:

n>= 10 or n<-1

remember for plotting...the < or > has a dotted line...and the >= or the <= has a solid line... to decided which side to shade...you plug in a value on either side of the line and see if that value satisfies the equation...if so...shade that region, if not..don't shade that region

Answer 2

Treat the >= just like an equals sign. Everything is the same. UNLESS YOU MULTIPLY OR DIVIDE BY A NEGATIVE NUMBER. In that case, turn the sign around.

n-10>=0
+10 +10
----------------
n>=10

-5+n<-6
+5 +5
---------------
n<-1

Answer 3

You could start by adding 10 to both sides for the first inequality

Answer 4

n-10>0
n > 10
-5+n<-6
n<-1
