2d) list 5 natural numbers of the form for some integer so one would be
1b) list all the x's such that x*y = 15, for some integer y. so one element of the set is 3, since 3*5 = 15., another is -3, since -3*-5 = 15
9a)correct.
I am lost in Discrete Mathematics. I do not know what is being asked for these two questions.
List five elements in each of the following sets:
2d.) {n Î N | n^{2} + n is a multiple of 3}
List the (distinct) elements in each of the following sets:
1b.) {x Î Z | xy = 15 for some y Î Z}
I would like verification if this is accurate:
9a.) List all the subsets of the set {a,b,c,d} that contain:
i.) four elements - {a,b,c,d}
ii.) three elements - {a,b,c}, {a,b,d}, {a,c,d}, {b,c,d}
iii.) two elements - {a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}
iv.) one element - {a}, {b}, {c}, {d}
v.) no elements - {0}
2d) list 5 natural numbers of the form for some integer so one would be
1b) list all the x's such that x*y = 15, for some integer y. so one element of the set is 3, since 3*5 = 15., another is -3, since -3*-5 = 15
9a)correct.
