Answer:
3.5, 4.2
Step-by-step explanation:
reflect make it not negative and its on y axis so y not affected
So firstly, we have to find out how many <em>are</em> green and yellow. For green subtract 17 from 20 and for yellow subtract 12 from 20:
- 20 - 17 = 3. 3 balls are green.
- 20 - 12 = 8. 8 balls are yellow.
Next, add up the total amount of balls that are green, yellow, and black:
- 8 + 3 + 5 = 16. 16 balls are not blue.
Lastly, subtract 16 from 20:
- 20 - 16 = 4. <u>4 balls are blue.</u>
At x=2, y=4
At x=4, y=16
So the total change in y from x=2 to x=4 is 16-4=12
And since average rate of change = total change in y divided by total change in x within the same period, therefore the answer is 12/2 = 6
