Question

Identify the variables in this Algebraic Expression X+ 4y - 9

Answer 1

Answer:

The expression $x + 4y - 9$ has two variables x and y.

Step-by-step explanation:

What is a variable?

A variable is a letter, for instance $x$ or $y$, that represents an unknown number.

Given the expression

$x + 4y - 9$

The given expression has three terms which are x, 4y, and -9.

Here:

• The term 'x' is the unknown variable x.

• The term '4y' has a coefficient (the number next to a variable y) of 4.

• The term '-6' is a constant.

As we already know that a variable is a letter, for instance x or y, that represents an unknown number. In other words, the values of x, or y are unknown to us.

Thus, the expression $x + 4y - 9$ has two variables x and y.
