Sample Response:
The algebraic expression has one constant, 10.2, which is a number by itself. The variables, which are letters that stand for unknown values, are x and y. The coefficients, which are numbers that are multiplied to the variables, are
-1, -1/2, and 1. The terms that have an x are like terms.
The given mathematical expression is combined by various parts.
The names are:
Those symbols whose value can vary(change, sometimes unknown to us thus possible to pertain one of multiple values)
They are of fixed value like 2, 4.4 etc.
If a constant is in multiplication with a variable, then such constant is called coefficient of that variable.
An algebraic expression is a mathematical expression obtainable by algebraic operations, variables and integers.
In an algebraic expression, the terms containing same variables with same power are called like terms.
[tex]-x + 10.2 -\dfrac{1}{2}x + y = -1 \times x + 10.2 -\dfrac{1}{2} \times x + y[/tex]
