The inverse of "if an angle is reflexive, then it is more than 270 degrees" is "if an angle is not reflexive, then it is not more than 270 degrees."

Suppose there is a simple index of three stocks, stock abc, stock xyz, and stock qrs. stock abc opens on day 1 with 4000 shares at $3.15 per share. stock xyz opens on day 1 with 5000 shares at $4.30 per share. stock qrs opens on day 1 with 6000 shares at $4.60 per share. the price of stock abc on day 8 begins at $3.50. the price of stock xyz on day 8 begins at $3.90. stock qrs opens on day 8 with a price of $4.50 per share. assume that each stock has the same number of shares that it opened with on day 1. what is the rate of change of this simple index over 1 week?

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

You decide instead to take the train there. the train will take 135 minutes. convert this into hours and minutes.
