Question 1

Which of the following is equivalent to |4x + 5| = 88?

-4x + 5 = 88

4x + 5 = -88

4x + 5 = 88

4x + 5 = 88 or 4x + 5 = -88

Question 2

Solve |6x – 5| = 25.

{5, -5}

{5, -10/3}

{-25, 25}

{10/3, -5}

Question 3

Which statement has the solution shown on the number line?

|x + 1| = 4

|x – 1| = 4

|x| = 3

none of the above

Question 4

Which statement is equivalent to |3x + 7| ≤ 30?

3x + 7 ≤ 30 or 3x + 7 ≥ -30

-30 ≤ 3x + 7 ≤ 30

3x + 7 ≤ 30

3x = 7 ≤ -30

Question 5

Solve |x+5| < 9.

{x| x < 4 or x > -14}

{x| x < 4 or x > -4}

{x| -14 < x < 4}

{x| -4 < x < 4}

Question 6

Which inequality has the solution shown on the number line?

|4 – x| ≤1

|x – 4| ≤ 1

|x + 2| ≥ 5

|x + 2| ≥ 7

Question 7

Which statement is equivalent to |x + 9| > 15?

x + 9 > 15

x + 9 < -15

x + 9 > 15 or x + 9 < -15

-15 < x + 9 < 15

Question 8

Solve |6x + 8| > 4.

{x| -4 < x < 4}

{x| -2 < x < -2/3}

{x| x > -2 or x < -2/3}

{x| x > -2/3 or x < -2}

Question 9

Which of the following has the solution shown on the number line?

|x + 3| ≤ 2

|x – 3| ≤ 2

|x + 3| ≥ 2

|x – 3| ≥ 2

Question 10

What is the solution of |x + 3| > -2?

x > 1 or x < -5

-5 < x < 1

all real numbers

no solution
