Let A = {1, 2, 3, 4, 5}, B = {1, 3, 5, 7, 9, 11} and U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}, then
a) A-B =
b) At =
c) (A ∩ B)t =
d) (A ∪ B)t=

Need on this geometry question. explain how you did it.

Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m? -15m = -4m -7m - 8 = m - 4 -3m - 8 = 4 - m m - 4 = -7m - 8 -8 - 7m = -4 + m -8 - 3m = 4 - m

Consider the sequence below. 3 , 1 , 1/3 , 1/9 , select the explicit function which defines the sequence.
