Answer: $\frac{6}{2}$

Step-by-step explanation:

1. Use this $\frac{f(b)-f(a)}{b-a}$ to find the average rate of change

2. Average rate of change = $\frac{f(8)-f(6)}{8-6}$

3. $f(8) = - 4$ and $f(6) = -10$ (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))

4. Replace -4 to f(8) and -10 to f(6)

5. So it will look like $\frac{-4-(-10)}{8-6}$

6. Solve $\frac{6}{2}$

Beth says that the graph of g(x) = + 1 is a translation of 5 units to the left and 1 unit up of f(x) = . She continues to explai

Nata [24]

Beth's description of the transformation is incorrect

<h3>Complete question</h3>

Beth says that the graph of g(x)=x-5+1 is a translation of 5 units to the left and 1 unit up of f(x) = x. She continues to explain that the point (0,0) on the square root function would be translated to the point (-5,1) on the graph of g(x). Is Beth's description of the transformation correct? Explain

<h3>How to determine the true statement?</h3>

The functions are given as:

g(x) = x - 5 + 1

f(x) = x

When the function f(x) is translated 5 units left, we have:

f(x + 5) = x + 5

When the above function is translated 1 unit up, we have:

f(x + 5) + 1 = x + 5 + 1

This means that the actual equation of g(x) should be

g(x) = x + 5 + 1

And not g(x) = x - 5 + 1

By comparison;

g(x) = x - 5 + 1 and g(x) = x + 5 + 1 are not the same

Hence, Beth's description of the transformation is incorrect

(5a +7b)b/(b+2b)=? <br> 4a ,4ab , 2a+4b , 5a+7b/3 , 5a+5b

musickatia [10]

The correct answer is: [D]: " $\frac{5a + 7b}{3}$ " .
__________________________________________________
Explanation:
__________________________________________________
$\frac{b(5a + 7b)}{b +2b}$ ;

Simplify the "denominator" ; → (b + 2b = 1b + 2b = 3b) ;

and rewrite:

$\frac{b(5a + 7b)}{3b}$ ;

Cancel out the "b" in the "numerator" to a "1" ;
and cancel the "3b" in the "denominator to a "3" ;

{since: "b ÷ b = 1 "; and since: "3b ÷ b = 3" } ;

and rewrite as:
____________________________________________________
$\frac{5a + 7b}{3}$ ;
____________________________________________________

→ which is: Answer choice: [D]: " $\frac{5a + 7b}{3}$ " .
____________________________________________________
