Answer:
Is it statement 3? It looks like it doesn't belong.
Multiply both sides by -8 to get k = -16
To check the solution, plug in -16 into the original equation. You do in-fact get 2
To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:

"d" represents the distance and coordinates are expressed as follows: (x, y)
Let's go to the calculations.
The answer is 10 uc.
Answer:
Note that it is not a perfectly elastic result so it is <em>irrational</em><em> </em>
