Answer:
- False
- True
- Maybe
- False
Step-by-step explanation:
I. [tex]\[x\text{ }\text{ }y\text{ }=\text{ }y\text{ }\text{ }x\][/tex]
If [tex]\[x\text{ }=\text{ }0,\text{ }y\text{ }\ne \text{ }0\][/tex]
Then, [tex]\[\text{ }\text{ }y\text{ }=\text{ }y\text{ }\][/tex]
The equation is not true for this case.
II. [tex]\[x\text{ }=\text{ }0,\text{ }y\text{ }=\text{ }0\][/tex]
Then, the equation will be satisfied.
III. [tex]\[x\text{ }\ne \text{ }0,\text{ }y\text{ }\ne \text{ }0\][/tex]
In this case the equation may or may not satisfy the condition depending upon the value of x and y.
IV. [tex]\[x\text{ }\ne \text{ }0,\text{ }y\text{ }=\text{ }0\][/tex]
Then, [tex]\[x\text{ }=\text{ }\text{ }x\][/tex]
The equation is not true for this case.
