A liquid starts at a temperature of 65 degrees and its temperature increases by a rate of 5 degrees per minute. How many minutes will it take for the temperature of the liquid to reach 128 degrees?

12.6 minutes

Step-by-step explanation:

We can write an equation to model this situation. Let x equal the minutes passed and y equal the temperature. We start out with 65 degree and add 5 degrees each minute, so we can write the equation:

65 + 5x  = y

We are looking for a temperature of 128, so we can substitute it in for y:

65 + 5x = 128

5x = 63

x = 12.6 minutes

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.
