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:

Add:

And that's our answer :)
(5,4)
x=5
y=4
hope this helped
mark brainliest :)
you question did not make sense so i assumed this is what you meant and needed.
D(1-1/4)
=3/4d
3/4d represents the money saved on a pillow
From the second:
2x-y=4
x=(4+y)/2 and applying this to first:
4+y+3y=12
4y+4=12
4y=8
y=2 and since x=(4+y)/2, x=3 so
x+y=2+3=5
