<h3>Answer: x+3</h3>
==============================================================
Explanation:
Use a graphing tool like Desmos to plot y = |x+3|
See below.
The graph is a V shaped figure. The vertex is at (-3,0). The interval x > 5 is entirely to the right of this vertex. So we only focus on the right hand side of the V shape.
The line making up this right hand side is the equation y = x+3
Therefore, if x > 5 then y = |x+3| becomes y = x+3
In short, we erase the absolute value lines.
This problem is represented in the Figure below. So, we can find the components of each vector as follows:
Therefore:
So:
Finally, the magnitude is:
