Line segment XY begins at (-6,4) and ends at (-2,4); XY is reflected over the x-axis and translated left 3 units to form line segment X'Y' which has a length of 4 units.
<h3>What is a system of equations?</h3>A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Line segment XY begins at (-6,4) and ends at (-2,4). Hence:
XY is reflected over the x-axis and translated left 3 units to form line segment X'Y'. Hence:
XY = X'Y' = 4 units
Line segment XY begins at (-6,4) and ends at (-2,4); XY is reflected over the x-axis and translated left 3 units to form line segment X'Y' which has a length of 4 units.

Answer:
AB = cm
Step-by-step explanation:
As we can see from the figure, BCDE is a square with each corner equal to 90°.
So that, BDE is a right triangle with corner BED equal to 90°
As BDE is a right triangle, according to Pythagoras theorem, we have:
cm
As the diagram s the cube, so that it can be seen that AD is perpendicular to the surface BCDE
=> AD is perpendicular to BD
=> ADB is the right triangle with corner ADB equal to 90°.
As ADB is the right triangle, ccording to Pythagoras theorem, we have:
cm
=> cm
Conclusion: AB = cm
