Answer:

C. 12

Step-by-step explanation:

Average rate of change = \frac{f(b) - f(a)}{b - a}

Where,

a = 1, f(a) = 3

b = 3, f(b) = 27

Average rate of change = \frac{27 - 3}{3 - 1}

Average rate of change = \frac{24}{2} = 12

Average rate of change for the interval from x = 1 to x = 3 is 12

Answer:

(2n + k) - 7

Step-by-step explanation:

1. Let ''a number'' be presented as n

2. ''twice a number'' → 2 n

3. ''twice a number and k'' → 2n + k

4. 7 less than twice a number → (2h + k) - 7

Help, answer one that hasn’t been answered
SVEN [57.7K]

4x + 2x = < y

This is because the opposite sides (which is 4x and 2x) of a triangle add up to the exterior angle (<y).

We have to find X.

As you know:

3x + 4x + 2x = 180

because the angles of a triangle add up to 180.

When we add them:

9x = 180

x =  \frac{180}{9}

The 9 is multiplying with the X. We want X only and not 9 with it. So, when we take 9 to the other side, it becomes divide. As a result, the answer to x is:-

x = 20

Substitute value of x into 4x and 2x to find the exterior angle:-

4x:

4(20) = 80

2x:

2(20) = 40

When we add them we get the answer for angle Y:-

80 + 40 = 120

Therefore, we can conclude that:

< y = 120 \: degrees
