Question

give some examples of variable,constant, coefficient​

Answer 1

Answer:

called a constant.

For example:

2, 5, 0, -3, -7, 2/7, 7/9 etc., are constants.

Number of days in a week represents a constant.

In the expression 5x + 7, the constant term is 7.

Variables:

A quantity which has no fixed value but takes no various numerical values is called a variable.

For example:

Temperature at different times of a day represents a variable.

The height of a student in your grade is a variable, as it varies from student to student. A variable is denoted by a letter like x, y, z, u, v etc.

A combination of a constant and a variable is also a variable.

Examples on Constants and Variables:

(i) In 2a, 2 is a constant and a is a variable.

(ii) In -7mn, -7 is a constant and m and n are variables.

(iii) In 3x, 3 is constant and x is variable but together 3x is a variable.

(iv) If 3 is a constant and x is a variable, then 3 + x, 3 - x, 3/x, 3x, x/3, etc., are also variables.

So, we conclude that the combination of a constant and a variable is always a variable.

Constants and Variables

Constants and Variables are the two types of symbols in algebra.

Constant:

A symbol which has a fixed numerical value is called a constant.

For example:

2, 5, 0, -3, -7, 2/7, 7/9 etc., are constants.

Number of days in a week represents a constant.

In the expression 5x + 7, the constant term is 7.

Variables:

A quantity which has no fixed value but takes no various numerical values is called a variable.

yes

For example: ex is easy

Temperature at different times of a day represents a variable.

The height of a student in your grade is a variable, as it varies from student to student. A variable is denoted by a letter like x, y, z, u, v etc.

A combination of a constant and a variable is also a variable.

Examples on Constants and Variables:

(i) In 2a, 2 is a constant and a is a variable.

(ii) In -7mn, -7 is a constant and m and n are variables.

(iii) In 3x, 3 is constant and x is variable but together 3x is a variable.

(iv) If 3 is a constant and x is a variable, then 3 + x, 3 - x, 3/x, 3x, x/3, etc., are also variables.

So, we conclude that the combination of a constant and a variable is always a variable.
