Answer:
A system of equations is when two or more equations have the same variable(s) that you work with together.
Step-by-step explanation:
For these types of equations, we typically use substitution, elimination, and graphing.
Answer:
$ 8.72
Step-by-step explanation:
- How much does Joe make per hour now?
$8.15 + 7%·$8.15 =
= $8.15 + 7×8.15/100
= $8.15 + $57.05/100
= $8.15 + $0.57
= $ 8.72
First picture:
You got the first two right (good job!), so I'll just tackle the third one. If you have to compute 
, it means that you have to substitute 
in place of 
. Differently from the first two points, this will generate a new function, rather than a specific value:
Second picture:
Given the point 
highlighted in the picture, you can deduce that the base is 
units long (since it spans from 
to 
) and the height is 
units long (because it spans from to ). So, the area of the rectangle is the multiplication between base and height:
But we know that 
, so we have
The domain of this function is given by the domain of the square root: we want its argument to be non, negative, so we have
But since the problem is symmetric, the answer is
You can only see the answer 
because, if you choose 
or 
, the rectangle degenerates to a segment, and your exercise doesn't like this scenario, apparently
Financial records are important records and thus, needs to be saved safely. The method for solid system to keep it is: Option d. I, II, and III
<h3>How to safely keep financial records and why?</h3>
Financial records are records of all financial transactions and receipts. They're needed for future cases like some contradictions, to get past details, to analyze data to make prediction about future sale and for development of the organization etc.
For keeping them, they should be saved in an easily accessible, and hardly destroy-able place. So that its prevented safely but accessible faster with correct authentication.
For the given case, for solid system for keeping financial records, we can actually follow all the three steps provided.
I. Making a mental note of all purchases made during the week. II. Recording money spent in a hand-held notebook. III. Organizing receipts and transactions on a computer.
Thus,
The method for solid system to keep it is: Option d. I, II, and III
