Answer:

Step-by-step explanation:
Answer:
X=2.5
Step-by-step explanation:
3x - 5 = 1/2x + 2x
3x - 1/2x - 2x = 5
1/2x = 5
X = 5 ÷ 1/2
X = 2.5
Y = -5x + 1
x = 1 , y = -4
x = 2 , y = -9
x = 3 , y = -14
so the answers are
(1,-4)
(2,-9)
(3,-14)
114
Just use the Pythagorean theorem and then multiply by 2 to find answer. See picture to see how I did it.
