Unit 1 Practice

Solve: -11 = n - 6

• 17 = n

• -17 = n

• 5 = n

• -5 = n

• a = -1.3

• a = 1.3

• a = 108

• a = -108

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

When you graph an inequality, you used a closed dot when you use which symbols?

• ≤, ≥ 
• <, >
• ≤, <
• ≥, >

When graphing an inequality, you use an open dot when you use which symbol?

• <, >
• ≤, ≥ 
• ≤, <
• ≥, >

Match the graph with its inequality.

• 11 < a
• 11 > a
•  11 ≤ a
•  11 ≥ a

Solve:
n - 2 ≤ 4

• n ≤ 2
• n ≤ 6
• n ≥ 6

-4x + 14 ≤ 54

• x ≥ - 10
• x ≤ -10
• x ≥ 10
• x ≤ 10
