Answers
10x + 3y = 11
We need to solve the system of equations.
x = pencils
y = notebooks
If we solve by graphing, we get the answer:
One pencil costs 0.50 dollars
One notebook costs 2.00 dollars

How do you get the y alone?
Answers
The answer is y = x-4.
Step-by-step explanation:
- The given expression is x-y=4
- Keep y alone on one side and move remaining terms to the other side.
⇒ -y = 4-x
- To have y alone, Multiply the above expression with -ve sign on both sides.
⇒ y = x-4

Answer:
The overall change in price of one share is: -$14.00
Step-by-step explanation:
The Acme Company share has declined its price in a rate of $3.50 per day
Therefore the change rate is:
In order to find the overall change in prince in 4 days in a row, we must have to multiply the change rate by 4 days
Therefore, the overall change in price is: -$14.00
3.5 per day for 4 days so multiply 3.5 by 4, which equals: $14
so the overall change is -$14.00

Ranking the three from best to worst will be: point, line, plane. The justification is that, the starting concept determines the next one.
Step-by-step explanation:
The connection can be described by starting with the fundamental concept,procedure or strategy that give rise to the others. In this case, to form a line, you need to have points that join to extend infinitely in different directions. This means the point, is the fundamental concept, that will give the line.A plane is an infinite set of points that form a connected flat surface extending infinitely far in all direction. So here again, the plane exist where there is a set of points. However, a plane is named by three points that are in the plane but not in the same line. Hence, before naming a plane, the concept of a line should be considered. Ranking the three from best to worst will be: point, line, plane. The justification is that, the starting concept determines the next one.
