Chapter 1.4, Problem 17E

To determine

To solve: the equation and graph the solution.

Answer to Problem 17E

The solution is $d=-5\text{ or }d=5$ and graphed the solution.

Explanation of Solution

Given:

  $\left|-3d\right|=15$

Calculation:

  $\begin{array}{l}\left|-3d\right|=15\text{ Given}\\ -3d=15\text{ or }-3d=-15\text{ Write two related linear equations}\\ \frac{-3d}{-3}\text{=}\frac{15}{-3}\text{ or }\frac{-3d}{-3}\text{=}\frac{-15}{-3}\text{ Subtract both sides of both equations by -3}\\ d=-5\text{ or }d=5\text{ Simplify}\end{array}$

  

Conclusion:

Therefore, the solution is $d=-5\text{ or }d=5$ and graphed the solution.
