Give the numerical coefficient of the term - 19x

Answer: The answer is - 19.

Step-by-step explanation: We are given to write the numerical coefficient of - 9x.

The given expression is a monomial with unknown variable 'x'.

We know that a numerical coefficient of a monomial is a constant multiplied to the variable (s). For example, in the term - 5xy, the unknown variables are 'x' and 'y' and the numerical coefficient is - 5.

Therefore, in - 9x, the unknown variable is 'x' and the numerical coefficient is - 9.

Thus, the answer is - 9.
