Represent One-Step Equations and Inequalities

Describe the graph for the solution for the following inequality:

a + 13 ≥ 20

• Closed circle; arrow pointing left

• Closed circle; arrow pointing right

• Open circle; arrow pointing left

• Open circle; arrow pointing left

Write an equation for the model above.

• x+3=−9

• 3x+1=9

• x−3=9

• 3x−1=9

Greg wrote in his math journal that 17 - x = 9 is an example of an algebraic equation. Which statement is true about the example Greg wrote in his math journal?

• Greg's example is an equation because there is a variable present.

• Greg's example is an equation because x can represent any value.

• Greg's example is an equation because it is a number sentence stating two amounts are equivalent.

• Greg's example is an equation because there are two numbers present.

x = 20

x = 7

x = 10

x = 3

• x = 20

• x = 7

• x = 10

• x = 3

Solve for b
2b = -16

• 8

• 4

• -8

• 3

-6x = 30

• x = - 5

• x = 24

• x = 5

• x = 36

Match the graph with its inequality.
