Question

Determine whether or not the given number is a solution to the given equation by substituting and then evaluating. |z|+1=-1 given that z=-8

Answer 1

Substituting z=-8 into the equation |z|+1=-1 and evaluating, we find that z=-8 is not a solution to the equation.

Step-by-step explanation:

To determine whether or not the given number, z=-8, is a solution to the equation |z|+1=-1, we substitute z=-8 into the equation and evaluate:

|z|+1=-1 \\ |-8|+1=-1 \\ 8+1=-1 \\ 9=-1

Since 9 does not equal -1, the equation is not satisfied. Therefore, z=-8 is not a solution to the equation.
