or 
is very easy to graph.
Choose whatever value of 
and use the same for 
in the same coordinate. Repeat and strike a line through all the points.
Some examples of valid points would be: 
, 
, 
and 
.
Then, to graph 
you have to look at it in terms of the equation of a line (
) and its parts.
In this case, 
and 
.
So, you choose any value for and you solve to find its counterpart.
I will start with 
:
Now, we have a first coordinate: 
.
Repeat with a different value:
It gives us the coordinates 
.
Plot those into the graph and strike a line through them.
Wherever the two lines in your Cartesian Plane cross, that is the solution for both equations. It should be 
.
You can check it by replacing and by "3" in both formulas and equating the values of :
Your solution is worked out and checked to be correct.
PS: I am attaching a picture of the graph, so you can have a visual idea of what it should look like.
The equation that represent the value of Alizeh’s investment after 20 years is y = 1000(b)^20
<h3>Exponential equation</h3>
The increase in the amount of his money can be represented using the exponential function as shown:
y = ab^x
Given the following
a = 1000
x = 20 years
Substitute
y = 1000(b)^20
Hence the equation that represent the value of Alizeh’s investment after 20 years is y = 1000(b)^20

Answer:
111 boxes
Step-by-step explanation:
He bought 223 feet of wood
Each box will take 2 feet
To determine the total number of box he'll make from 223,
1 box = 2 feet of wood
X box = 223 feet of wood
X = (223 × 1) / 2
X = 111.5 box approximately 112 boxes
But technically, since its 111.5, he'll be able to make 111 boxes completely with 0.5 feet of wood left
We gotta know the rate she went to know how long it took her
