P Systems of Inequalities

2. Solving Systems of Inequalities
A system of Inequalities is a set of two or more Inequalities that use the same variables.
The solution is the (x, y) that works in both (all) of the Inequalties.
(The Graph will be a Region.)
> or < use a dashed line
> or < use a solid line
If y is > or > shade above the line
If y is < or < shade below

3. Use Normal inequality rules to Graph multiple inequalities.
x + 2y > 4
y > 2x + 1

4. An Entrance exam has two parts, a verbal part and a mathematics part
An Entrance exam has two parts, a verbal part and a mathematics part. You can score a maximum total of 1600 points. For admission, the school of your choice requires a math score of at least Write a system of inequalities to model scores that meet the school's requirements. Then solve the system.

5. Verbal + Math < 1600
Math > 600
Let x = verbal
Let y = math
x + y < 1600 or (y < x)
y > 600

6. College Admissions
x + y < 1600 or (y < x)
y > 600

7. y > - | x + 2 | + 5
y > 3
