Answer:
13
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [2, 6 ]
f(b) = f(6) = 6² + 5(6) - 8 = 36 + 30 - 8 = 58
f(a) = f(2) = 2² + 5(2) - 8 = 4 + 10 - 8 = 6
Hence
average rate of change = = = 13
23 + 12x <= 75
12x <= 52
if you want an integer, answer is 4 hours
if fractions of an hour are allowed than the answer is 4 and 1 / 3 or 13 / 3

Answer:
x=2
Step-by-step explanation:
move x to the 3x side and move 5 to 9 side.
you get 2x=4
then you divide 2 from both sides and get 2
Step-by-step explanation:
Step 1:
Let us consider the given expression
On Right Hand Side of equation,
Using BODMAS rule, we could get 2.4 as value.
Step 2:
Now let us consider the Left Hand Side of equation and solve it
which will be equal to 2.4.
