Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x ----> the number of open acres
y ----> the number of developed acres
we know that
-----> inequality A
The solution of the inequality A is the shaded area above the solid line 
-----> inequality B
The solution of the inequality B is the shaded area below the solid line 
so
The graph in the attached figure
Answer:
Is a consistent independent system
Step-by-step explanation:
we know that
If a system has at least one solution, it is said to be consistent .
If a consistent system has exactly one solution, it is independent .
If a consistent system has an infinite number of solutions, it is dependent
If a system not have solution, it is said to be inconsistent
we have
----> equation A
----> equation B
----> equation C
substitute equation A and equation B in equation C

Solve for z

The solution is the point (5,6,11)
The system has only one solution
therefore
Is a consistent independent system
Yes, 13•150=1950 and then 11•60=660 so combined they equal 2610
