Answer 1

Давайте решим данную систему уравнений графическим способом:

Система уравнений: 1. x - y = -5 2. 2x + 5y = 4

Для решения системы уравнений графически, давайте представим каждое уравнение в виде функции и построим их графики на координатной плоскости.

1. Первое уравнение: x - y = -5 Перепишем его в виде y = x + 5. Это уравнение представляет собой прямую с наклоном 45 градусов, проходящую через точку (0, 5) и имеющую положительный наклон.

2. Второе уравнение: 2x + 5y = 4 Перепишем его в виде y = (-2/5)x + 4/5. Это уравнение представляет собой прямую с отрицательным наклоном, проходящую через точку (0, 4/5).

Теперь построим графики обоих уравнений на одной координатной плоскости:

Для первого уравнения (y = x + 5), мы можем начать с точки (0, 5) и провести прямую, которая идет вверх с наклоном 45 градусов.

Для второго уравнения (y = (-2/5)x + 4/5), начнем с точки (0, 4/5) и проведем прямую, которая идет вниз с отрицательным наклоном.

Графики обоих прямых пересекутся в одной точке. Пересечение графиков соответствует решению системы уравнений.

Точка пересечения графиков (-29/3, -14/3) является решением данной системы уравнений.
