Answer:
Part 1) No solutions
Part 2)
part 3)
Step-by-step explanation:
Part 1) we have
-------> equation A
-------> equation B
Multiply the equation A by
-------->
Equation A and equation B represent parallel lines
therefore
Is a inconsistent system of equations
The system has no solution
Part 2) we have
-------> equation A
-------> equation B
Multiply equation A by
------> ------> equation C
Multiply equation B by
------> ------> equation D
Adds equation C and equation D
Part 3) we have
-------> inequality A
-------> inequality B
we know that
If a ordered pair lie in the solution set of the system of inequalities
then
the ordered pair must be satisfy the system of inequalities
case A)
substitute the value of x and the value of y in both inequalities
Verify inequality A
-------> is true
Verify inequality B
------> is not true
the point is not a solution
case B)
substitute the value of x and the value of y in both inequalities
Verify inequality A
-------> is not true
the point is not a solution
case C)
substitute the value of x and the value of y in both inequalities
Verify inequality A
-------> is true
Verify inequality B
------> is true
the point is a solution
case D)
substitute the value of x and the value of y in both inequalities
Verify inequality A
-------> is not true
the point is not a solution
1- no solution
2- 7
3-
