Answer:
Step-by-step explanation:
Step one:
given data
we are told you earn $1200
the linear function for the cost is expressed as
y=1200x-----------------1
Step two:
We want to bring out the following information
Independent: The number of screens which is x
Dependent: The total revenue which is y
Function: y=1200x
What is a dependent variable?
This is a variable that rely on the value of other terms
What is a independent variable?
this is a variable that does not rely on other terns
Area=legnth times width
42=legnth times width
a quilt is normally for a big bed probably at leas 3 feet wide
factor 42
42=2 times 3 tiesm 7
possible values are
2 by 21
3 by 14
6 by 7
I would go with the 6 by 7 format
You are looking for the shaded region that would be contained in both of the inequalities.
You have:
![x+y \leq 80](https://tex.z-dn.net/?f=x%2By%20%5Cleq%2080)
![5x+10y\ \textgreater \ 500](https://tex.z-dn.net/?f=%205x%2B10y%5C%20%5Ctextgreater%20%5C%20500)
If you graph an shade the correct half-plane for those equations, you will see there is a triangular region on the left side of the first quadrant.
