Transcribed Image Text:Determine vwhether each statement is true or false. If a statement is true, give a reason or cite an appropriate statement from the text. If a statement is false, provide an example that shows the statement is not true in all cases or cite an appropriate statement from the text.

O True, there is always the trivial solution, when all variables are equal to 0.
O True, there is always the trivial solution, when all variables are written in terms of t.
O True, there is always the trivial solution, vhen all variables are equal to 1.
O False, consider the following system:
5x - 8y = 0
3x + y = 0.
O False, consider the following system:
2x + 4y = 0
9x + y = 0.
