Q 9 Linear Equations and Inequalities

Any new equation obtained by raising both member of an equation to the same power may have solutions is called

• extraneous solutions

• absolute value

• radical signs

• simultaneous equation

If x = 0 then | x | is equal to

• X

• 0

• 1

• -X

The symbols < , > , ≤, ≥ are called

• equality symbols

• inequalities symbols

• operational signs

• radical signs

The solution of 4x-2 > 6 is

• x > 2

• x < 6

• x = 4

• x > 4

| 5 | should be equal to

• 5

• -5

• 0

• 1 / 5

In √(2x-3) - 7 = 0, the value of x should be

• 24

• 26

• 23

• 20

When the variable in an equation occurs under a radical, the equation is said to be

• quadratic equation

• radical equation

• linear equation

• fraction

For real number ‘x’ the absolute value is denoted by

• x³

• | x |

• 1 ⁄ x

• −t

To add or subtract a positive number from both sides of any inequality without any change in the inequality sign is called

• distributive property of inequality

• multiplicative property of inequality

• additive property of inequality

• transitive property of inequality
