Answer:
The solutions to the system of equations are:

Step-by-step explanation:
Given the system of the equations

isolate 'x' for 2x-y

Add y to both sides


Divide both sides by 2



isolate 'y' for 


subtract y from both sides


Divide both sides by 9






The solutions to the system of equations are:

Since the ratio is 3:4 there are a total of 7 parts. Divide the 581by 7 to find that each part is 83.
Answer:
.

Step-by-step explanation:
From Mathematics we remember that the domain of a functions corresponds to the set of values of the independent variable (
in this case) so that images exist and the range of a function is the set of images.
In this case, we know the domain and range of
and we must find the domain and range of
.
Domain
The domain of
is the domain of
. That is,
.
Range
We have to define the bounds of the range of
, given that range
is modified by streching and horizontal translation operations:
Lower bound (
)

Upper bound (
)

In consequence, the range of
is 
A-$70 is the correct answer, even though im not sure.
