1. Choose a number greater than 8, substitute for y and solve:
Solving an inequality
12+𝑦 >20
− −12
Check:
𝑦 >8
Choose a number greater than 8,
substitute for y and solve:
12+10 >20
TRUE
22>20

2. Graphing the solution y >𝟖
Open circle on 8 means it does not include 8
Arrow points right to include all
numbers greater than 8

3. Choose a number greater than 9, substitute for x and solve:
Solving an inequality
8𝑥≥72
Check:
𝑥 ≥9
Choose a number greater than 9,
substitute for x and solve:
8(10) ≥72
TRUE
80≥72

5. Choose a number greater than -5, substitute for t and solve:
Solving an inequality
−20𝑡≤ 100
− −20
Check:
𝑡 ≥ −5
Choose a number greater than -5,
substitute for t and solve:
20 0 ≤100
TRUE
0≤100

6. Graphing the solution t ≥−𝟓
Closed circle on -5 means it does include -5
Arrow points right to include all
numbers greater than -5
