On a school trip 32 freshman, 48 Sophomores, and 60 juniors. Students from each grade level are to ride each bus. If the students from each grade level are divided equally among the buses, what is the greatest number of buses that can be used for the trip?

Answer:

x=−5,y=50

Step-by-step explanation:

Answer:

Step-by-step explanation:

try setting it up like this: 14 times x minus 20 then get x and y alone do the same for the second question

Solve for f(x) using both 4 and 8:

f(x) = 4+6 = 10

f(x) = 8+6 = 14

Find the difference between the answers:

The difference between the two answers is 14-10 = 4

Find the difference between the interval:

The difference between 4 and 8 is: 8-4 = 4

The rate of change is the change in the answers over the difference in the interval:

The rate of change is 4/4 = 1

Answer:  

The Average rate of change for f(x) = x+6 over the interval (4,8) is 1

Solution:  

We define the Average rate of function f(x) over the interval (a, b) as

  --- eqn 1

From question, given that

f(x) =x+6 --- eqn 2

The interval is (4,8) .hence we say a = 4 and b = 8

The average rate of change for f(x) = x + 6 is given by using eqn 1

--- eqn 3

Where, by using eqn 2 , we get f(8) = 8+6 =14 and f(4) = 4+6 =10

Such that the required value would be f(8)-f(4) = 14-10 = 4

By substituting the values of f(8) and f(4) in eqn 3 ,the average rate of change for the given expression is  

Hence the Average rate of change for f(x) = x+6 over the interval (4,8) is 1

My answer is the same as the one above.
