A biologist studying bacteria finds that when the bacteria are exposed to ultraviolet light, the population can be modeled by an exponential decay function with 9% as the
rate of decrease.
Which could be the function that models the bacteria population?

-A: y=9(0.09)^x
-B: y=48(1.9)^x
-C: y=255(1.09)^x
-D: y=360(0.91)^x

Determine whether the points (–3,–6) and (2,–8) are in the solution set of the system of inequalities below. x ? –3 y < 5? 3x + 2 a. the point (–3,–6) is not in the solution set, and the point (2,–8) is in the solution set. b. neither of the points is in the solution set. c. the point (–3,–6) is in the solution set, and the point (2,–8) is not in the solution set. d. both points are in the solution set.
