Explanation:</h2>
In this case we have the following system of inequalities:

First of all, let's plot the equations:


From:

The symbol ≥ tells us that the shaded region (the red one) lies above the line and includes all the points on the line.
From:

The symbol ≤ tells us that the shaded region (the green one) lies under the line and includes all the points on the line.
Therefore, the graph that stands for this problem is shown below. As you can see, there is no intersection between the two shaded regions, so there is no any solution there.

Answer:
12
Step-by-step explanation:
This triangle is a 3-4-5 Pythagorean Triple. 9 is 3*3, 15 is 5*3, so b is 4*3, which is 12. Alternatively, you could use the Pythagorean Theorem's converse, sqrt(15^2-9^2), and get 12.
