You can use a number line to subtract -6 from -7. The difference is -1.
Answer:
and 
in interval notation.
Step-by-step explanation:
We have been given a compound inequality 
. We are supposed to find the solution of our given inequality.
First of all, we will solve both inequalities separately, then we will combine both solution merging overlapping intervals.
Dividing by negative number, flip the inequality sign:
Dividing by negative number, flip the inequality sign:
Upon merging both intervals, we will get:
Therefore, the solution for our given inequality would be and in interval notation.
Answer:
1. -72
2. -66

Hope this helps you :)
In this case if x<100 George will be losing money. So he will only earn a profit when he sells more than 100 DVDs. Essentially (x-100) represents his break-even point.
Answer:
