Answer:
For A, both equations have the same slope, but different y-intercepts. This means that they are parallel, and will never cross, meaning there is no solution.
For B, it's the same equation, meaning that they are always crossing (it's the same line!), so there are infinite solutions.
Answer:
The length of one side of the square is 11.8 inches.
Step-by-step explanation:
Since a square has 4 sides and they are all equal, you want to divide 47 by 4.
You will get 11.75 inches per side.
However, since they want you to round to the near tenth, the answer will actually be 11.8 inches.
Your sequence appears to be geometric with a common ratio of 2. It can be described by
a(n) = (-2 2/3)·2^(n-1)
_____
This can be written in a number of other forms, including
a(n) = (-8/3)·2^(n-1)
a(n) = (-1/3)·2^(n+2)
a(n) = (-4/3)·2^n
