Find the average rate of change for the function f(x) =x^2 -6x+2 on the closed side interval (-5,2)

Answer:

- 9

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [a, b ] = [ - 5, 2 ], thus

f(b) = f(2) = 2² - 6(2) + 2 = 4 - 12 + 2 = - 6

f(a) = f(- 5) = (- 5)² - 6(- 5) + 2 = 25 + 30 + 2 = 57 , thus

average rate of change = \frac{-6-57}{2-(-5)} = \frac{-63}{7} = - 9

-4 = r divided by 20 − 5<br> Solve for R
Sidana [21]

Answer:

20

Step-by-step explanation:

Simplify both sides of the equation.

−4= r 20 −5 −4= 1 /20 r+−5 −4= 1 /20 r−5

Flip the equation.

1 /20 r−5=−4

Add 5 to both sides.

1 /20 r−5+5=−4+5

1 /20 r=1

Multiply both sides by 20.

20*( 1 /20 r)=(20)*(1)

r=20

Y = 7x − 7z − 9 Solve for X
Novay_Z [31]
Y= 7x - 7z -9
+9             +9             Y+9+7z /7=x
Y+9 = 7x - 7z
+7z          +7z
Y+9+7z = 7x
