Answer:
to find the permiter of the shapes add up all the sides
to find the area multiply one of the sides and another side
instead of changing the 5/7 u change the 3/4
So,
1. Graph each inequality separately.
2. Choose a test point to determine which side of the line needs to be shaded.
3. The solution to the system will be the area where the shadings from each inequality overlap one another (purple area)
As for the system of inequalities we say it's unbounded.
5x+19=6x+1 because of parallel postulate.
x=18
