A material has an initial quantity of 15 units. Which equation models the amount of the material, y, decaying exponentially at a rate of 23% over time, X? y = 23(1.15)
y = 23(.85)x
y = 15(1.23)x
y = 15(.77)x

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
