Nis a two-digit number. the lowest common multiple (lcm) of 84 and n is 504, find n

What is the solution to the system of equations? (–2, –8) (–1, –5) (0, –2) (2, 4)

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1
