We will show that the reflexive closure of a transitive closure of a relation is equal to the transitive closure of its reflexive closure through a series of simpler results: [3 marks] let ribe a transitive relation on a set s, show that its reflexive closure rr is also transitive. [3 marks] let rΔ be a reflexive relation on a set s, show that its transitive closure tr, is also reflexive. [3 marks] using the previous results or otherwise, show that r(tr) = t(rr) for any relation r on a set. hint: you may find the fact that transitive (resp. reflexive) closures of r are the smallest transitive (resp. reflexive) relation containing r useful.

The monthly texting plan of all star cell is $11 per month and $0.25 per text. the monthly texting plan of top line cell is $14 per month and $0.15 per text. a student wants to set up a system of equations to find the number of texts for which the total monthly cost of the two companies is the same. he uses the variables x and y. he lets y represent the total monthly cost. what will x represent? x = number of texts x = cost of the total number of texts x = total monthly cost x = cost of each text
