Answer:

The beginning balance of Sophie's account is 75
Step-by-step explanation:
Using the slope intercept form aka 
The slope of a line describes how steep a line is.
- We can see that the y-axis goes up by 25.
- 25, 50, 75, 100, 125, 150 etc
<u>$ is how much you have in your bank account.</u>
<em>We can see that Sophie starts off with 75 dollars.</em>
In the first week, we see that Sophie has 100 dollars. In the second week, we see that Sophie has 125.
<h3>how to find the slope</h3>

The first week (1, 100)
The second week (2,125)

Answer:
(1)
And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:


And replacing we got:

And the width for this case would be 15.8 in
Step-by-step explanation:
For this case we know that the photo is rectangular. Let's define:
x = the width, y= the length
And we know that the perimeter is given by:
(1)
And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:


And replacing we got:

And the width for this case would be 15.8 in
Graph four shows the increase
The answer to this is - 2(56x-1)/ 7x
