Answer:
x= -5
Step-by-step explanation:
-4 (x +3) = 8
-4x - 12 = 8
-4x = 20
x= -5
As the intervals moves from left to right on the graph, the average rate of change increases
<h3>How to determine the change in the rate of change?</h3>
The function is an exponential growth function.
This is known because it has an initial value at (0, 2), and the value increases to the right
The average rate of change of exponential growth functions increases towards the right.
This means that:
The initial statement is "as the intervals moves from left to right on the graph, the average rate of change increases
Because the average rate of change keeps changing, the final statement is:
Since the average rate of change is also changing, the function is changing and approaches infinity

Answer:
x = 19
Step-by-step explanation:
All triangle angles equal 180
3x + 9 + 2x + 4x = 180
9x + 9 = 180
9x = 171
x = 19
Answer:
A
Step-by-step explanation:
Slope intercept form is y = mx + b
First find the slope or m with this equation
(plug in)
=
= ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
So your slope is ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
To find the y-intercept you use y= mx + b and plug in.
6 = 1/4(12) + b
6 = 3 + b (minus 3 on both sides)
3 = b
so 3 is the y-intercept
So the answer is A.
-6.9=y/3-2.1
let's get y by itself
Add 2 1 to both sides
-4.8=y/3
Multiply both sides by 3
-14.4=y
If you want to check if this is right plug into the original equation
-6.9=-14.4/3-2.1
-6.9=-4.8-2.1
-6.9=-6.9
answer holds true :)
