What are Inequalities?
Inequalities are a comparison of number or variables that use <,>,≤,≥
X+8<15
X < 7
3x + 3 ≥ -12
x ≥ -5
-5x > 20
X < -4
What do these symbols mean: <,>
<:Less than
>:Greater than
Y - 3 ≥ 5
Y ≥ 8
9x - 2 > 25
X > 3
-2x > 14
x < -7
What do these symbols mean:≥,≤
≤: Less than or equal to
≥: Greater than or equal to
3X > 12
X > 4
3n - 5 ≤ -23
n ≤ -6
-4x < 8
What are solutions and how many do inequalities have?
A solution is an answer to the problem. Inequalities have multiple solutions.
X/2 < 4
X < 8
3x - 4 ≥ 8
X ≥ 4
-5x≤10
x ≥ -2
What is the rule when multiplying or dividing by a negative number?
When multiplying or dividing by a negative number, you must flip the symbol.
x + 15 ≤ 12
X ≤ -3
5x + 7 ≤ 22
X ≤ 3
-2x<30
x>-15
