Answer:

Step-by-step explanation:
To find the distance between any two points, we can use the distance formula.
The distance formula is:

Let (2,8) be x₁ and y₁ and let (7,7) be x₂ and y₂. Thus:

Simplify:

Square:

And that's our answer :)
8 X
----- = ------
20 40000
40000/20=2000
2000*8=16000
X=16000
Answer:
x = -7
Step-by-step explanation:
Subtract 15 from both sides of the equation.
x = 8 -15 = -7
Answer:
y = 5x – 22
3x + 2y = 34
