Write the Coefficients of x from these
+
2x + 8y
+9​

Answer 1

Given :- Write the Coefficients of x from these

A) 2x + 8y

3) 7x + 9

Answer :-

we know that,

• Coefficient is a number that is used to multiply the variables .

so,

→ Coefficient of x in 2x + 8y = 2 * x + 8 * y = 2

and,

→ Coefficient of x in 7x + 9 = 7 * x + 9 = 7

SOLUTION

TO DETERMINE

The Coefficients of x from 2x + 8y + 9

CONCEPT TO BE IMPLEMENTED

Algebraic expressions :

A combination of constants and variables , connected by four fundamental arithmetical operations i.e addition , subtraction , multiplication and division is called an algebraic expressions

Terms :

Various parts of an algebraic expression , which are separated by + or – are called terms of the algebraic expression

Coefficients :

In a term of an algebraic expression the numerical factor of a term is called coefficients and any of the factors with the sign of the term is called coefficient of the product of the other factors

EVALUATION

Here the given algebraic expression is

$\sf{2x + 8y + 9}$

In the given expression there are 3 terms

The terms are 2x , 8y , 9

Now x occurs in the term 2x

Since in the term 2x the variable x is multiplied by the numerical factor 2

Hence the required coefficient of x = 2

FINAL ANSWER

The Coefficients of x from 2x + 8y + 9 is 2
