In the inequality 3 > 0, what does the symbol '>' represent?

  1. Greater than

  2. Less than

  3. Equal to

  4. Not equal to


Correct Option: A
Explanation:

The symbol '>' in the inequality 3 > 0 represents 'greater than'. It indicates that the value on the left side (3) is greater in magnitude or quantity than the value on the right side (0).

Consider the inequality 5 - 2 < 3. What is the relationship between the values on the left and right sides of the inequality?

  1. The left side is greater than the right side.

  2. The left side is less than the right side.

  3. The left side is equal to the right side.

  4. The relationship cannot be determined.


Correct Option: B
Explanation:

In the inequality 5 - 2 < 3, the left side (5 - 2) evaluates to 3, which is less than the value on the right side (3). Therefore, the relationship between the values is 'less than'.

If x is a variable, what does the inequality x > 0 imply?

  1. x is a positive number.

  2. x is a negative number.

  3. x is zero.

  4. x can be any real number.


Correct Option: A
Explanation:

The inequality x > 0 implies that the variable x is greater than zero. This means that x must be a positive number.

In the inequality 2x - 5 ≤ 0, what values of x satisfy the inequality?

  1. x ≤ 2.5

  2. x ≥ 2.5

  3. x = 2.5

  4. None of the above


Correct Option: A
Explanation:

To solve the inequality 2x - 5 ≤ 0, we need to isolate x. Adding 5 to both sides, we get 2x ≤ 5. Dividing both sides by 2, we get x ≤ 2.5. Therefore, the values of x that satisfy the inequality are those less than or equal to 2.5.

Consider the inequality -3x + 4 > 7. What is the smallest integer value of x that satisfies the inequality?

  1. -1

  2. 0

  3. 1

  4. 2


Correct Option: D
Explanation:

To solve the inequality -3x + 4 > 7, we need to isolate x. Subtracting 4 from both sides, we get -3x > 3. Dividing both sides by -3 (reversing the inequality since we are dividing by a negative number), we get x < -1. The smallest integer value that satisfies this inequality is -2.

If a > b and b > c, what can we conclude about the relationship between a and c?

  1. a > c

  2. a < c

  3. a = c

  4. The relationship cannot be determined.


Correct Option: A
Explanation:

Since a > b and b > c, we can conclude that a is greater than b, and b is greater than c. By the transitive property of inequalities, we can infer that a is also greater than c. Therefore, the relationship between a and c is a > c.

In the inequality 2x + 3 ≥ 5, what is the largest integer value of x that satisfies the inequality?

  1. 0

  2. 1

  3. 2

  4. 3


Correct Option: B
Explanation:

To solve the inequality 2x + 3 ≥ 5, we need to isolate x. Subtracting 3 from both sides, we get 2x ≥ 2. Dividing both sides by 2, we get x ≥ 1. The largest integer value that satisfies this inequality is 1.

Consider the inequality 4 - 2x ≤ 6. What values of x satisfy the inequality?

  1. x ≤ 1

  2. x ≥ 1

  3. x = 1

  4. None of the above


Correct Option: A
Explanation:

To solve the inequality 4 - 2x ≤ 6, we need to isolate x. Subtracting 4 from both sides, we get -2x ≤ 2. Dividing both sides by -2 (reversing the inequality since we are dividing by a negative number), we get x ≥ -1. Therefore, the values of x that satisfy the inequality are those greater than or equal to -1.

If x is a variable, what does the inequality x ≤ 0 imply?

  1. x is a positive number.

  2. x is a negative number.

  3. x is zero.

  4. x can be any real number.


Correct Option:
Explanation:

The inequality x ≤ 0 implies that the variable x is less than or equal to zero. This means that x can be either a negative number or zero.

In the inequality 3x - 2 > 8, what is the smallest integer value of x that satisfies the inequality?

  1. 3

  2. 4

  3. 5

  4. 6


Correct Option: B
Explanation:

To solve the inequality 3x - 2 > 8, we need to isolate x. Adding 2 to both sides, we get 3x > 10. Dividing both sides by 3, we get x > 10/3. The smallest integer value that satisfies this inequality is 4.

Consider the inequality -2x + 5 < 1. What values of x satisfy the inequality?

  1. x > 2

  2. x < 2

  3. x = 2

  4. None of the above


Correct Option: A
Explanation:

To solve the inequality -2x + 5 < 1, we need to isolate x. Subtracting 5 from both sides, we get -2x < -4. Dividing both sides by -2 (reversing the inequality since we are dividing by a negative number), we get x > 2. Therefore, the values of x that satisfy the inequality are those greater than 2.

If a > b and b = c, what can we conclude about the relationship between a and c?

  1. a > c

  2. a < c

  3. a = c

  4. The relationship cannot be determined.


Correct Option: A
Explanation:

Since a > b and b = c, we can conclude that a is greater than b, and b is equal to c. By the transitive property of equality, we can infer that a is also greater than c. Therefore, the relationship between a and c is a > c.

In the inequality 5x - 3 ≥ 12, what is the largest integer value of x that satisfies the inequality?

  1. 2

  2. 3

  3. 4

  4. 5


Correct Option: B
Explanation:

To solve the inequality 5x - 3 ≥ 12, we need to isolate x. Adding 3 to both sides, we get 5x ≥ 15. Dividing both sides by 5, we get x ≥ 3. The largest integer value that satisfies this inequality is 3.

Consider the inequality 2 - 3x ≤ 4. What values of x satisfy the inequality?

  1. x ≤ 2

  2. x ≥ 2

  3. x = 2

  4. None of the above


Correct Option: A
Explanation:

To solve the inequality 2 - 3x ≤ 4, we need to isolate x. Subtracting 2 from both sides, we get -3x ≤ 2. Dividing both sides by -3 (reversing the inequality since we are dividing by a negative number), we get x ≥ -2/3. Therefore, the values of x that satisfy the inequality are those greater than or equal to -2/3.

If a > b and b > 0, what can we conclude about the relationship between a and 0?

  1. a > 0

  2. a < 0

  3. a = 0

  4. The relationship cannot be determined.


Correct Option: A
Explanation:

Since a > b and b > 0, we can conclude that a is greater than b, and b is greater than 0. By the transitive property of inequalities, we can infer that a is also greater than 0. Therefore, the relationship between a and 0 is a > 0.
