If 0xy, then x2y2.arrow_forwardIn Exercises , prove the statements concerning the relation on the set of all integers. 17. If and , then .arrow_forwardIn Exercises , prove the statements concerning the relation on the set of all integers. 14. If and , then .arrow_forward
- Let be a relation defined on the set of all integers by if and only if sum of and is odd. Decide whether or not is an equivalence relation. Justify your decision.arrow_forwardGive an example of a relation R on a nonempty set A that is symmetric and transitive, but not reflexive.arrow_forwardIn Exercises 610, a relation R is defined on the set Z of all integers. In each case, prove that R is an equivalence relation. Find the distinct equivalence classes of R and list at least four members of each. xRy if and only if x+3y is a multiple of 4.arrow_forward
- In Exercises , a relation is defined on the set of all integers. In each case, prove that is an equivalence relation. Find the distinct equivalence classes of and list at least four members of each. 10. if and only if .arrow_forwardLabel each of the following statements as either true or false. If R is an equivalence relation on a nonempty set A, then any two equivalence classes of R contain the same number of element.arrow_forwardIn Exercises 610, a relation R is defined on the set Z of all integers, In each case, prove that R is an equivalence relation. Find the distinct equivalence classes of R and least four members of each. xRy if and only if x2y2 is a multiple of 5.arrow_forward
