What is a variable?

Question

Verified by Toppr

Answer 1

A variable is a symbol or letter, such as $x$ or $y$ , that represents a value. In algebraic equations, the value of one variable is often dependent on the value of another. Hence it's a symbol that takes various numerical values.

e.g. in the polynomial $x + 5, x$ is a variable.

Answer 2

A variable is a symbol or letter, such as

x

or

y

, that represents a value. In algebraic equations, the value of one variable is often dependent on the value of another. Hence it's a symbol that takes various numerical values.

e.g. in the polynomial

x + 5, x

is a variable.

What is a variable?

A symbol that takes a fixed numerical value.

A symbol that takes various numerical value.

A symbol some time fixed and some time variable.

cannot be determined.

What is the output of $x^{2} + 3 x + 5$ , where $x$ (variable) = $2$ ?

The variable in the polynomial $x^{2} + 3 x + 5$ is:

Identify the variable from the equation $z + 12 = 24$

Identify the variable from the equation, $(t - 7) > 5$ ?

What is the output of $x^{2} + 3 x + 5$ , where $x$ (variable) = $- 1 ?$
