It would be C! If you use use the distributive property. it would equal 8x+20=8x+20 indicating it is infinity

What is the rate of change from x = n to x = 2n?

puteri [66]

Answer:

$\dfrac{-8}{\pi}$

Step-by-step explanation:

The rate of change of the function f(x) from point $x_1$ to point $x_2$ can be calculated using formula

$\dfrac{f(x_2)-f(x_1)}{x_2-x_1}$

Given

$x_1=\pi\\ \\x_2=2\pi$

From the graph of the function

$f(x_1)=f(\pi)=4\\ \\f(x_2)=f(2\pi)=-4$

So, the rate of change is

$\dfrac{f(x_2)-f(x_1)}{x_2-x_1}=\dfrac{-4-4}{2\pi -\pi}=\dfrac{-8}{\pi}$

There were 48 peaches in a carton. The average mass of all the peaches was 0.17 kg. What was their total mass?

alexira [117]

Answer:

8.16 Kg

Step-by-step explanation:

average is calculated as

average = $\frac{sum}{count}$

here average = 0.17 and count = 48 , then

0.17 = $\frac{sum}{48}$ ( multiply both sides by 48 )

8.16 = sum

that is total mass = 8.16 Kg

In the figure below, o ll g. Find the values of x and z. (42 - 16 • 1 84

Reika [66]

Answer:

x = 96

z = 28

Step-by-step explanation:

Given:

(4z - 16) , 84, o║g

Proof

X = 180 - 84 (Sum of Opposite angles is 180)

x = 96

Let's take ∠(4z - 16) as ∠A

∠A = ∠X (Vertically opposite angles)

(4z - 16) = 96

4z = 96 + 16

4z = 112

z = 112/4

z = 28
