True or False<\/h1>\n

If you think the statement is true, then show that it is true. On the other hand, if you think the statement is false, then give an example that disproves the statement. For example, the statement “If A and B are matrices of the same order, then A – B = B – A” is false and an example that disproves it is <\/p>\n<\/p>\n

Such an example is called a\u00a0counterexample.<\/p>\n

1. True or false: A system comprising two linear equations in two variables has a unique solution if and only if the straight lines represented by the equations are nonparallel.<\/li>\n
2. True or false:\u00a0Suppose the straight lines represented by a system of two linear equations in two variables are parallel to each other. Then the system has infinitely many solutions.<\/li>\n
3. True or false: If\u00a0A<\/i>\u00a0and\u00a0B<\/i>\u00a0are matrices of the same order, then <\/li>\n
4. True or false: If\u00a0A<\/i>\u00a0and\u00a0B<\/i>\u00a0are matrices such that\u00a0AB<\/i>\u00a0and\u00a0BA<\/i>\u00a0are both defined, then\u00a0A<\/i>\u00a0and\u00a0B<\/i>\u00a0must be square matrices.<\/li>\n
5. True or false: If\u00a0A<\/i>\u00a0is a square matrix with inverse and\u00a0c<\/i>\u00a0is a nonzero real number, then\n

6. True or false: If\u00a0AX = B<\/i>\u00a0is a system of\u00a0n<\/i>\u00a0linear equations in\u00a0n<\/i>\u00a0unknowns and \u00a0 does not exist, then\u00a0AX = B<\/i>\u00a0does not have a unique solution.<\/li>\n<\/ol>\n
