Question

Differentiate between:1. Constants and variables2. Literal coefficients and numerical coefficients

Answer 1

Step-by-step explanation:

1.

A constant refers to the known values in an expression or equation. It is written or represented as a number.

On the other hand, variables refer to the unknown values in an expression or equation. It is written or represented by letters or symbols

For example:

`\begin{gathered} 3x+2y=12 \\ where: \\ 3x=a\text{ }variable \\ 2y=a\text{ }variable \\ 12=constant \end{gathered}`

2.

Literal coefficients refer to the coefficients of a term present in an equation or expression represented by a variable. It is used to represent a number

Numerical coefficients refer to number(s) that is/are the multiplier of the variables in a term

For example:

`\begin{gathered} 6xyz \\ where: \\ 6=numerical\text{ }coefficient \\ x=literal\text{ }coefficient\text{ }of\text{ }6yz \\ xy=literal\text{ }coefficient\text{ }of\text{ }6z \\ xyz=literal\text{ }coefficient\text{ }of\text{ }6 \end{gathered}`
