A. set the top equation as x=something. you can do this by transforming functions.
answer x=2y-8
Then you substitute 2y-8 for x in the bottom problem. 4(2y-8) - 8y= 10.
Solve for y. you will get a false equation. -32=10. Proved.

B. we know that the lines are parallel. if the line don't have a solution that means that they don't intersect. that means they must be parallel because parallel lines never intersect.

Ratling [72]

Answer:

d=20/3 or 6.6 repeating

Step-by-step explanation:

Let's solve your equation step-by-step.

What is the relationship between translations, reflections, and ridgid motion?

vivado [14]

The relationship between translations, reflections, and rigid motion is that they are all types of rigid motions, which means their size does not change.

<h3>What exactly is rigid motion?</h3>

Rigid motion is the movement of a set in which the distance between points remains constant.

<h3 /><h3>What is translation?</h3>

Translation is a type of rigid motion in which an object simply slides while maintaining its direction.

<h3 /><h3>What do you mean by reflection?</h3>

A reflection, like a mirror, causes an image to flip to another location.

We must establish a connection between translations, reflections, and rigid motion.

We can conclude from the above definitions that the size of the object remains constant, but it is undergoing different transitions.

Therefore, Translations, reflections, and rigid motion all belong to the category of transformations that are rigid motions, which means that their sizes don't change.
