Point F on the coordinate grid is reflected across a line to create point F’. Then, points E, F, and F’ I connected to create a triangle. kari says Point E must be on the perpendicular bisector of the line FF’, regardless of the line across which point F was reflected. enter a equation of a line Across which F could be reflected to support Kari claim or enter the equation of a line across which F could be reflected a show that kari’s claim is incorrect.

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?
