2. x=6 pounds/ 2/9pounds
3. x=6 pounds * 9/2 pounds
4.x=27 guests
Variable: r constant: 7 coefficient: -2 and 8
Answer:
The average rate of change is 4
Step-by-step explanation:
To find the values of y when x = 0 and when x = 2, we can graph the equation using a graphing calculator.
Looking at the graph, we can see that when x = 0 y = 5 and when x = 2 y = 13
Now that we have two points (0,5) and (2,13) we can find the rate of change
To find the rate of change we use this equation: 
Let's input the values from our two points

Simplify:
= 4
