Answer:
120
Step-by-step explanation:
We are given that the function for the number of students enrolled in a new course is .
It is asked to find the average increase in the number of students enrolled per hour between 2 to 4 hours.
We know that the average rate of change is given by,
,
where f(x)-f(a) is the change in the function as the input value (x-a) changes.
Now, the number of students enrolled at 4 = f(4) = = 255 and the number of students enrolled at 2 = f(2) = = 15
So, the average increase = = = 120.
Hence, the average increase in the number of students enrolled is 120.
Step-by-step explanation:
Combine common terms
(3x²+5x²)+(7x-4x)+(-5+11)
8x²+3x+6
There are 10000 bugs and you add 15 bugs to it.
10,000+15= 10,015
The total is 10,015 bugs
There were already 10,000 bugs and 15 bugs joined them.
Which makes it an addition statement
