(x1, y1) = (10+√55/5, 5-2√55 /5)
(x2, y2) = (10-√55/5, 5+2√55 /5)
Объяснение:
x^2 + y^2=16
2x + y=5
x^2 + y^2 = 16
y= 5-2x
x^2 +(5-2x)^2 = 16
x=10+√55 /5
x=10-√55 /5
y=5-2*10+√55 /5
y=5-2*10-√55 /5
y=5-2√55 /5
y=5+2√55 /5
(x1, y1) =(10+√55 /5, 10-√55 /5)
(x2, y2) =(10-√55 /5, 10+√55 /5)
(10+√55 /5) ^2, (5-2√55 /5) ^2 =16
2*10+√55 /5 + 5-2√55 /5 =5
(10-√55 /5) ^2, (5+2√55 /5) ^2 =16
2*10-√55 /5 + 5+2√55 /5 =5
16=16 16=16
5=5 5=5
(x1, y1) = (10+√55/5, 5-2√55 /5)
(x2, y2) = (10-√55/5, 5+2√55 /5)
