Answer:

x=7

Step-by-step explanation:

AC=3x+3 AB=-1+2x and BC=11

AC = AB + BC

ALL THE STEPS:

3 X + 3 = - 1 + 2 X + 11

3 X + 3 = 2 X + 10

3 X + ( - 2 X ) + 3 = 2 X + ( - 2 X ) + 10

X + 3 = 10

X + 3 + ( - 3 ) = 10 + ( - 3 )

X = 7

Answer:

Average rate of change is -78.

Step-by-step explanation:

A talent competition on television had five elimination rounds. After each elimination, only one-third of the contestants were sent to the next round.

The table that shows the number of contestants in each round of the competition is,

x f(x)

1 243

2 81

3 27

4 9

5 3

Average rate of change is the change in the y-value divided by the change in the x-value for two points on the graph.

i.e $\dfrac{f(x_2)-f(x_1)}{x_2-x_1}$

So, the average rate of change of $f(x)$ from $x = 1$ to $x = 4$ is,

$=\dfrac{f(4)-f(1)}{4-1}$

$=\dfrac{9-243}{4-1}$

$=\dfrac{-234}{3}$

$=-78$

Since f(x) is decreasing, so rate of change is negative.
