Find each sum.
Greeley [361]

Answer:

Sum is - 5n² -8n + 4.

Step-by-step explanation:

Given : (3n² – 5n + 6) + (–8n²– 3n – 2) .

To find : Sum .

Solution : We have (3n² – 5n + 6) + (–8n²– 3n – 2) .

Combine like terms :

(3n² - 8n²– 5n - 3n + 6 - 2).

- 5n² -8n + 4.

Therefore, Sum is - 5n² -8n + 4.

Find the average rate of change of k(x)=5x–19 over the interval [<br> -<br> 14,<br> -<br> 4].
rusak2 [61]
The rate of change of a function can be modeled with the following expression:

\frac{\Delta{k{x)}}{\Delta{x}}

Where Δx is the change in x value, and Δk(x) is the corresponding change in k(x). We're given the two extremes of x, so we can calculate the change in x to be

\Delta{x}=-4-(-14)=10

To find the change in k(x), we can calculate the values of k(x) at x = -14 and x = -4 and find the difference between them:

k(-14)=5(-14)-19=-70-19=-89\\ k(-4)=5(-4)-19=-20-19=-39\\ \Delta{y}=k(-14)-k(-4)=-89-(-39)=-50

So, the rate of change for the function from x = -14 to x = -4 is

\frac{\Delta{y}}{\Delta{x}}= \frac{-50}{10}=-5
