СРОЧНО!!!! ОЧЕНЬ НАДО!!!!! ПОЖАЛУЙСТА!!!!!​

Answer 1

$left { {{y = -x -1} atop {x=-(x - 1)^{2} + 4}} right. \-x -1 = -(x-1)^2 +4\x= -1\x=4\y=-(-1)-1\y = -4 -1\y = 0\y = -5\left { {{0=-(-1)-1} atop {0=-(-1-1)}^2 + 4} right. \left { {{-5=--4-1} atop {-5=-(4-1)^2 + 4} right. \left \\left { {{0=0} atop {0=0}} right. \left { {{-5=-5} atop {-5=-5}} right. \(x_{1}, y_{1} } ) = (-1, 0)\(x_{2}, y_{2} ) = (4, -5)$
