1. Problem Description
The problem asks to solve the compound inequality and graph the solution on the number line.
2. Solution Steps
First, we need to isolate in the inequality . We can do this by subtracting 3 from all parts of the inequality:
Now, we divide all parts of the inequality by . Remember that when we divide or multiply by a negative number, we need to reverse the inequality signs:
We can rewrite this as:
This means is greater than and less than or equal to .
To graph the solution on the number line, we use an open circle at because is strictly greater than , and a closed circle at because is less than or equal to . We draw a line connecting these two points.
3. Final Answer
The solution to the inequality is .
On the provided number line, draw an open circle at and a closed circle at , and draw a line segment connecting the two circles.
