How many solutions does an inequality have?

Like systems of equations, system of inequalities can have zero, one, or infinite solutions. If the set of solutions includes any shaded area, then there are indeed an infinite number of solutions.

What are the 4 properties of inequality?

Properties of inequality

  • Addition property: If x < y, then x + z < y + z.
  • Subtraction property: If x < y, then x − z < y − z.
  • Multiplication property:
  • z > 0. If x < y, and z > 0 then x × z < y × z.
  • z < 0. If x < y, and z < 0 then x × z > y × z.
  • Division property:
  • It works exactly the same way as multiplication.
  • z > 0.
