Semester 2 - Unit 1 Test Review

Solve 2x - 3 = 1 

• 3
• 2
• 1
• -2

Solve   -3x + 5 = -16

• 9
• 8
• -7
• 7

Solve  9 + 3x = 10

• 2/3
• 1/3
• -1/3
• 4

What is the first step to solve this equation:
-11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

Solve for x.

• x = 21
• x = 7
• x = −21
• x = 4

WRITE AN EQUATION
Aliyah had $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?

• 24-10=7x
• 24-7x=10
• 10+7x=24
• 10+x=14

What inequality does the number line graph represent?

• x >= 3
• x > 3
• x < -3
• x <= 3

What inequality does the number line graph represent?

• 2x +1 < -3
• x + 2 < 4
• -x + 3 > 1
• x + 4 >= 2

Does the given value make the inequality true?  x + 9 > 21, when x = 15

• True
• Not True

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

• ≤, ≥ 
• <, >
