5

Step-by-step explanation:

on day 1 you had 20 pieces and each day you lose 2 pieces. so that means your equation is y=-2x+20. So x = number of days, and y = pieces of candy. Plug in 10 for y, minus 20 to both sides, divide by -2 to each side. Then your answer is 5.

step-by-step explanation:

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
