Answer:
The dependent variable is y (the amount paid)
Step-by-step explanation:
Given

The dependent variable
From the question, we have:
This means that the value of y is determined by the value of x.
Take for instance:
The value of y will be:
If x changes (say; x = 12), y will also change
<em>Hence, y is the dependent variable</em>
5+2=7
Multiply each side by 3.
7(9x + 3) = 30
Expand the brackets
63x + 21 = 30
Subtract both sides by 21
63x = 9
Divide both sides by 63
X = 1/7

How to graph the inequality?</h3>
Here we want to graph the inequality:
x ≤ -5
This refers to all the values of x equal or smaller than -5.
To graph this, we need to graph a closed circle at -5, and we need to draw an arrow that points to the left (values smaller than -5). The graph is the one that you can see below.
The interval notation that defines this set is: (-∞, -5]
The first end is open, and the second is closed (because of the symbol ≤).

<span>Stephen and Aaron solved the same equation using two separate methods. Their work is shown in the table below:
Stephen Aaron:
3x - 2 = 5x - 6 3x - 2 = 5x - 6
3x - 2 + 2 = 5x - 6 + 2 3x - 3x - 2 = 5x - 3x - 6
3x = 5x - 4 -2 = 2x - 6
3x - 5x = 5x - 5x - 4 -2 - 6 = 2x
-2x = -4 -8 = 2x
x = 2 -4 = x
Identify who made the error and what he did wrong.
Aaron made the error when he subtracted 6.
Aaron made the error when he subtracted 3x.
Stephen made the error when he added 2.
Stephen made the error when he subtracted 5x.
answer:
</span>In the Aaron`s work:
- 2 = - 2 x - 6
and after that:
- 2 - 6 = 2 x
It should be:
- 2 + 6 = 2 x
or: - 2 + 6 = 2 x - 6 + 6
Answer:
A ) Aaron made the error when he subtracted 6.
It changes every 1 5 degrees because 10 divided by 5 is 2
I hope this helped ya :)
