Question
Consider the relation R = {(x, y) | x, y ∈ Z+ and x + y = 10}. Determine which of the following statements is true.a. R is a Symmetric Relationb. None of the Option is correctc. R is a Transitive Relationd. R is a Antisymmetric Relatione. R is a Reflexive Relation
Solution
To determine the type of relation, we need to check the properties of each type of relation:
a. Symmetric Relation: A relation R on a set A is said to be symmetric if (a, b) ∈ R implies that (b, a) ∈ R, for all a, b ∈ A. In this case, if we take (x, y) = (3, 7) which belongs to R because 3 + 7 = 10, but (7, 3) does not belong to R because 7 + 3 = 10 is not true. So, R is not a symmetric relation.
b. None of the Option is correct: We need to check all the options before we can determine this.
c. Transitive Relation: A relation R on a set A is said to be transitive if whenever (a, b) ∈ R and (b, c)
