Answer:
2.56
Step-by-step explanation:
Monday: 2 * 2.21 = 4.42
Tuesday: 4.42 + 0.39 = 4.81
Wednesday: 4.81 - 1.76 = 3.05
Thursday: 3.05 - 1/5 * 3.05 = 3.05 - 0.61 = 2.44
Friday: 2.44 + 0.12 = 2.56
Answer: The average rate of change is 1 over 3, or just 1/3. The y-values change 1 unit every time the x-values change 3 units, on this interval! hope this helps
Add 1 to both sides of the equation to get 4x = 4.
Divide both sides by 4 and <em>x = 1</em>.
Is that the right equation?
