Answer 2

Correct Question: Coefficient of $z$ in $5-\frac{1}{2}z$ is

Answer:

The coefficient of variable $z$ in the polynomial $5-\frac{1}{2}z$ is the number $-\frac{1}{2}$.

Step-by-step explanation:

Coefficient: Any number or the alphabets which are multiplied by the variable and written before the variable is called coefficient (of that variable).

For example: In a linear polynomial, $ax+b=0$.

Here, the alphabet $a$ is written before the variable $x$.

Thus, $a$ is the coefficient of variable $x$.

Consider the given equation as follows:

$5-\frac{1}{2}z$

Rewrite the equation as follows:

⇒ $5+\left(-\frac{1}{2} \right)z$

Then using the definition of coefficient, we get

The number $-\frac{1}{2}$ is the coefficient of variable $z$.

Therefore, the coefficient of variable $z$ in the polynomial $5-\frac{1}{2}z$ is the number $-\frac{1}{2}$ .
