Explain this and what method? Is it linear combos or some sort of GCF finding

just subtracting the expression for revenue from the expression for cost

Step-by-step explanation:

  2x^3 + 30x - 130

-  2x^3 - 3x - 520

(subtracting means adding the opposite)

2x^3 - 2x^3 = 0

30x - (-3x) = 33x

-130 - (-520) = 390

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.
