Question

The value of -20²÷ 5xy is ---------------

(A) 4²

(B) 4y

(C) 4xy

(D) -4yz​

Answer 1

Answer:

Coefficient of x in 4x-y is 4

Coefficient of x in 8-x+y is -1

Step-by-step explanation:

In this question,

Coefficient is a numerical or Constant quantity multiplying the variable in algebraic expression.

Coefficient of x in 4x-3y is 4 as 4 is the constant multiplying the variable.

Coefficient of x in 8-x is -1 as -1 is the constant multiplying the variable.

We can't say Coefficient of x iny^{2}x-y\ y^{2}y

2

x−y y

2

as y is itself a variable.

Similarly in 2z-5xz as z is itself a variable.

Therefore, Coefficient of x in the following expression are 4 and -1
