• Shift down

Describe the transformations that were applied to the parent function.

 $y=3\left|x\right|+8$  

• Reflection over the x-axis

• Vertical stretch (narrower)

• Compression (wider)

• Shift left

• Shift up

Find the solution to the following system of equations:

3x + 2y + z = 0

2x - 4y - 6z = 8

5x + 10y - 15z = 20
