Answer:
(Price x 0.20) + price
Step-by-step explanation:
To find a certain percentage of something, move the decimal on the percent 2 places to the left and multiply that by the original number
If something is marked up by a certain price, that means you’re adding to it so you just have to add whatever 20% of the item is to the original cost
• The following formula can be used to find the slope of a line:
These points are on the line:
Given the following points:
Then, you can set up that:
Therefore, substituting values into the formula and evaluating, you get:
• As you can notice, the slope is negative. Therefore, you can determine that it is decreasing.
Therefore, the answers are:
• Slope of the line:
• It is decreasing.
Answer:
y = 1/2x + 2
Step-by-step explanation:
<u>Solving for y in steps:</u>
- 2x - 4y + 8 + 4y= 4y
- 2x + 8 = 4y
- x + 4 = 2y
- y = x/2 + 4/2
- y = 1/2x + 2
Yes, because if you round up or round down it'll be 0.02 or 0.01.
If you put them on the number line, it'll between 0 and 1.
By definition:
- If a system has at least one solution, it's said to be consistent.
- If a system has exactly one solution, it's independent.
- If a system has infinite solutions, it's dependent
- If a system has no solutions, it's inconsistent.
Your system has exactly one solution (the two lines represent the two equations, and the point where they meet is the solution of the system), and so it is consistent, and in particular independent.
