Determine the average rate of change of f (x) = x² - 10x + 5 over the interval [-4, 4]. = -

jeka57 [31]

Answer:

f ( x ) = ( x - 5 ) ² - 20

Step-by-step explanation:

1- Add the same value to both sides

f ( x ) = x ² - 10x + 5

2- Add 25 to the expression

f ( x ) + ? = x ² - 10x + ? + 5

3- Add 25 to the left-hand side

f ( x ) + ? = x ² - 10x + 25 + 5

4- Factor the expression

f ( x ) + 25 = x ² - 10x + 25 + 5

5- Move the constant to the right

f ( x ) + 25 = ( x - 5 ) ² + 5

6- Calculate

f ( x ) = ( x - 5) ² + 5 - 25

Are the fractions 1/5 , 5/5 , and 5/1 equivalent?Explain.

NeX [460]

Answer:
They are not equal

Explanation:
Let's take a look at each one of them separately:
 $\frac{1}{5}$ : This fraction is in the simplest form. It is equivalent to 0.2
The fraction is formed by dividing one part over five

 $\frac{5}{5}$ : This fraction is not in the simplest form. We can divide 5 by 5 and the answer would be 1. Therefore, $\frac{5}{5}$ is equivalent to 1

 $\frac{5}{1}$ : This fraction is not in the simplest form. We can divide 5 by 1 and the answer would be 5. Therefore, $\frac{5}{1}$ is equivalent to 5.

Based on the above, we can cnfirm that 0.2 , 1 and 5 are not equivalent.
Therefore, the given fractions are not equivalent

Hope this helps :)
