10 ! without graphing, classify the system as independent, dependent, or inconsistent. y=-x+5 and x-y=-3

Which of the following can be used to explain a statement in a geometric proof?

Which of the following is a solution of z^6 = 64i? 2(cos105° + isin105°) 2(cos120° + isin120°) 2(cos135° + isin135°) 8(cos15° + isin15°)

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
