Q. Solve for

k

.

\newline

0 = 4|k|

\newline

Write your answers as integers or as proper or improper fractions in simplest form.

\newline

k =

_____ or

k =

_____

Find Absolute Value of $k$ : $0 = 4|k|$ $\newline$ Find the value of $|k|$ . $\newline$ Divide both sides by $4$ . $\newline$ $0 / 4 = (4|k|) / 4$ $\newline$ $0 = |k|$ $\newline$ $|k| = 0$
Divide by $4$ : $|k| = 0$ $\newline$ Find the values of $k$ . $\newline$ If $|x| = a$ , then $x = a$ and $x = -a$ . $\newline$ However, since $|k| = 0$ , we know that $0$ is the only number that when taken absolute value equals $0$ . Therefore, $k = 0$ and $k = -0$ (which is the same as $k = 0$ ). $\newline$ Values of $k$ : $0$ and $0$
