Ответ:
Let
x------> represents the number of AA batteries
y------> represents the number of 9V batteries
we know that
The constraints are
so
--------> inequality A
--------> inequality B
so
-----> inequality C
The solution of the system of inequalities is the shaded area in the attached figure
If a ordered pair meet all the constraints and make sense in the context of the situation, then the ordered pair is a solution of the system of inequalities
let's check each of the ordered pairs
case A) point
Verify inequality A
--------> is true
Verify inequality B
-------> is true
Verify inequality C
------> is true
The ordered pair meets all restrictions, therefore the ordered pair is a solution of the system of inequalities
case B) point
Verify inequality A
--------> is true
Verify inequality B
-------> is true
Verify inequality C
------> is not true
The ordered pair does not meet all the restrictions, therefore the ordered pair is not a solution of the system of inequalities.
case C) point
Verify inequality A
--------> is true
Verify inequality B
-------> is not true
Verify inequality C
------> is not true
The ordered pair does not meet all the restrictions, therefore the ordered pair is not a solution of the system of inequalities.
case D) point
Verify inequality A
--------> is true
Verify inequality B
-------> is true
Verify inequality C
------> is true
The ordered pair meets all restrictions, therefore the ordered pair is a solution of the system of inequalities
the answer is
