Find the sum of 15 and the difference between 9 and 5 step by step

15 + 4 = 19 or 15 - 4 = 11

Step-by-step explanation:

Sum of 15 are: 6 and 9, 7 and 8, 8 and 7, 9 and 6

9+6 = 15

8+7 = 15

The difference between 9 and 5 is 4.

9-5 = 4

5-9 = -4

In all

15 + 4 = 19 or 15 - 4 = 11

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.
