Answer:

p=9

Step-by-step explanation:

8*4p+8*5

32p+8*5

32p+40

8(5p-4)

multiply the numbers:8*5=40

8*5p-8*4

Multiply the number 8*4=32

40p-8*4

40p-32

32p+40=40p-32

Subtract 40p from both sides:

32+40-40=40p-32-40

Simplify:

-8p=-72

divide both sides by: -8

-8p/-8=-27/-8

p=9

cupoosta [38]

9m+2=3m-10
subtract 3m from both sides to get:
6m+2=-10
subtract 2 from both sides to get:
6m=-12
finally, divide by 6 on both sides to get what m equals:
m=-2

What is the average rate of change of f(x) = -x2 + 3x + 6 over the interval –3

Rufina [12.5K]

Answer:

$\frac{\Delta y}{\Delta x} =\frac{f(x_2)-f(x_1)}{x_2-x_1} =\frac{6-(-12)}{3-(-3)} =\frac{18}{6}= 3$

Step-by-step explanation:

To find the average rate of change of a function over a given interval, basically you need to find the slope. The mathematical definition of the slope is very similar to the one we use every day. In mathematics, the slope is the relationship between the vertical and horizontal changes between two points on a surface or a line. In this sense, the slope can be found using the following expression:

$Average\hspace{3}rate\hspace{3}of\hspace{3}change=Slope=\frac{y_2-y_1}{x_2-x_1} =\frac{f(x_2)-f(x_1)}{x_2-x_1}$
