Answer:
The graph is attached.
Step-by-step explanation:
Let be "x" the number of metamorphic samples and "y" the number of sedimentary samples.
You know that you want to to have at most 25 samples, then:
And you want to have at least 3 times as many sedimentary samples as
metamorphic samples, then:
Therefore, the system of inequalities that model the situation is:
The y-intercept of the line is:
And the x-intercept is:
Knowing this, you can graph the line
The y-intercept of the line is:
And the x-intercept is:
Knowing this, you can graph the line.
Observe the graph attached, where the solution of the system of inequalities is the intersection of the regions.
