5/x = 4/8

Simplify the fraction 4/8

Divide both the numerator and denominator by 4 to get 1/2

5/x = 1/2

Now, we cross multiply: a/b = c/d ⇒ ad = bc

5/x = 1/2
1(x) = 5(2)
x = 10

Your final answer is D. 10.

Cross-multiply for a result of:

40=4x

Divide by 4 to see that x=10. D is the correct answer.

What is the average rate of change of the function from x = 0 to x = 2?.

irina1246 [14]

The average rate of change of the function from x = 0 to x = 2 is -2

From the complete question (see attachment), we have the following ordered pair when x = 0 and x = 2

$(x,y) = \{(0,10)\ (2,6)\}$

The average rate of change is calculated using:

$\Delta x = \frac{y_2 -y_1}{x_2 -x_1}$

So, we have:

$\Delta x = \frac{6-10}{2-0}$

Evaluate common terms

$\Delta x = \frac{-4}{2}$

Divide -4 by 2

$\Delta x = -2$

Hence, the average rate of change of the function from x = 0 to x = 2 is -2
