Determine the average rate of change
Average rate is calculated as thus;

<em>In this case; b = 12 and a = 6</em>
Calculating f(12)



Calculating f(6)



Substitute 12 for b and 6 for a in 

Substitute values for f(6) and f(12)

Step-by-step explanation:
Answer: Choice C) Multiplication property of inequalityThe rule basically says that if you start with a < b and you multiply both sides by some positive number c, then a*c < b*c. The sign doesn't flip if you multiply both sides by a positive number.
The sign will flip if c is negative. So we'll go from a < b to a*c > b*c if c is negative.
Example 1:
1 < 5
-2 > -10 ... multiplied both sides by -2; sign flips
Example 2:
3 < 7
9 < 21 ... multiplied both sides by 3; sign does not flip
Similar rules apply to a > b,

and
Because each ticket costs 1 and she spends 8 she would be buying 8 tickets
She has 8 friends so each one would get 1 ticket
The answer is 1
