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
Answer:
1.Triangle is heavier than a square.
2.Circle is lighter than the triangle and square.
3.3 squares won't be balanced between one triangle.
Step-by-step explanation:
Imagine Triangle is 10 and Square is 3
Triangle is heavier.
Imagine Circle is 1
3+3+3=9 also 3 squares
3 squares + 1 circle = 10
as one circle equals 1.
