Answer:
n > 3
Explanation:
−2n − 3 < −9
First, we can get rid of the -3 by adding it to both sides.
−2n − 3 < −9
+ 3 +3
The three's cancel out, and -9 + 3 = -6.
Now we are left with −2n < −6.
We can divide -2 from both sides.
−2/-2 n < −6/-2
The two's cancel out, and -6/-2 = 3.
However, since we divided by a negative number we must flip the sign.
The final product is n > 3.
Graph:
Place an open circle at 3. The circle is open because it is just a greater than sign, and the circle is only closed if we have a less than or equal to than sign or a greater than or equal to than sign. Simply a greater than or equal to sign will be a closed circle. Once the open circle is placed at 3, draw the arrow pointing to the right, since n is greater than 3. To the right we have all numbers greater than 3.
The graph may look like this:
