100 POINT REWARD TO HELP WITH ANSWER FOR 15. Help

I'm using <= as "less than or equal to", and >= as "greater than or equal to".

Let x = speed

For a car, it has to be at least 45: x >= 45 and it has to be at most 65: x <= 65

When you put these two together you have

solution: let us assume that the distance from town A to town B is 100 miles

65l.g 100=65 miles

t1= 1h

t2=35/v

total time=4tt2

(17 35/v) hr.

average speed=total distance/total time

50= 65+35/1+35

50=100/v+35

50/1=100v/v+35

answer is 35.

step-by-step explanation:

because mean value defines that total sum value over total number of set

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.
