Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.
y = 2700(0.453)^x

Josh has a rewards card for a movie theater he receives 15 points for becoming a rewards card holder he earns 3.5 points for each visit to the movie theater he needs at least 55 points to earn a free movie ticket which inequality can josh use to determine x, the minimum number of visits he needs to earn his first free movie ticket.

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
