Answer:
6
Step-by-step explanation:
Use the slope formula:

Picking x = 2 and x = 4 as my two points (since the interval is 2 ≤ x ≤ 4), we get:

So, the BEST estimate of the average rate of change for the function given in the table is 6.
4(3)^2-3(3)+7
36-9+7
34
g(3)=34
Answer:
Width = x² + 5x - 4
Step-by-step explanation:
By the definition of an area model,
Area = Width × greatest common factor
Since, Area = 4x² + 20x - 16
And greatest common factor = 4
4x² + 20x - 16 = 4(Width)
By dividing both the sides of the equation by 4,

x² + 5x - 4 = Width
Therefore, width = (x² + 5x - 4) will be he answer.
Answer:
3x+2y=2x+8
3x-2x+2y=8
3x-2x=8-2y
x=8-2y
B(w) = 12; Katy will have read 12 books after w weeks
b(2) = 10; the number of books that Katy will have read in 2 weeks is 10
b(3) = f; the number of books that Katy will have read after 3 weeks is f
Remember w is just number of weeks!!
