< less than ≤ less than or equal to (line underneath sign)
> greater than ≥ greater than or equal to (line underneath sign)
# is just the number they gave you in the inequality
x < # [you can put any number into "x", but it has to be less than #]
x > # [you can put any number into "x", but it has to be greater than #]
x ≤ # [number has to be less than or equal to #]
x ≥ # [number has to be greater than or equal to #]
1. t < 7 [t is a number less than 7]
So you circle: 4, 6, 8, 0, -6
3. a ≤ -4 [a is a number less than or equal to -4]
circle: -7, -4
5.
k + 5 < 9 You can simplify this by subtracting 5 on both sides
k < 4 [k is a number less than 4]
circle: -1, 3, -2, 3.5
7. u - 5 ≥ -1 Simplify
u ≥ 4 [u is a number greater than or equal to 4]
circle: 4, 5, 4.1
