Answer 1

К сожалению, я не имею доступа к приложенным фотографиям или графикам. Однако я могу помочь вам решить задачи, которые вы предоставили, текстовым способом. Вот решения ваших задач:

1. Решение системы уравнений: a) Графически: Постройте графики обеих уравнений и найдите точку пересечения. b) Подстановка: Решите одно уравнение относительно одной переменной и подставьте это значение в другое уравнение. c) Сложение: Сложите оба уравнения так, чтобы одна из переменных ушла, и найдите значение другой переменной.

2. Решение уравнения о количестве ткани: Пусть "x" - количество ткани на одно платье, "y" - количество ткани на один сарафан. Запишите систему уравнений и решите её.

3. Решение системы уравнений: Раскройте скобки, соберите по одной стороне уравнений, выразите одну переменную через другую и подставьте в другое уравнение. Решите полученное уравнение.

4. Уравнение прямой: Используйте координаты точек S(7, 4) и N(-3, 14), чтобы найти угловой коэффициент "k" и свободный член "b" в уравнении прямой y = kx + b.

5. Система уравнений: Подставьте значение одной переменной из одного уравнения в другое и решите полученное уравнение.

Если у вас есть конкретные вопросы по этим задачам, пожалуйста, уточните, и я буду рад помочь вам.
