What is a variable, constant term, and numerical coefficient?

 

Variables: is the unknown or the quantity represented by any letter.

Examples: 5y+3; the letter y is the variable

example: 9c; the letter c is the variable

example: 2x-8; x is the variable

Numerical Coefficient: the number along with the variable. It is what you multiply a variable by.

example: 3y+7; the numerical coefficient is 3y is 3.

example: 8c; the numerical coefficient of 8c is 8.

example: 5+3m; the numerical coefficient of 3m is 3.

Constant: is a number that does not change..

Example: 5+3m; 5 is the constant , it's a number by itself therefore this number never changes.

Example: 4x-3; 3 is the constant term, it's a number by itself therefore it never changes.

Example: 7n-5; 5 is the constant term, it's a number by itself therefore it never changes.
