Во вложении находится графическое решение: пересечение графиков функций y = x² - 1 и y = 2x. Эти графики пересекаются в двух точках, при x ≈ -0,4 и при x ≈ 2,4
Если быть точнее, то решением будет х = -0,414 и х = 2,414

20 балов. Решите тесты по английскому языку. I went to the cinema last week and laughed all the way through the new film "Waiter!" which is set in a restaurant.The American actor Tom Waters plays the worst cook the world has ever seen and he employs one of the worst waiters, played by Joe Vermont/
The London restaurant where the filming took place does actually exist.
Jane Connors, the owner, runs a successful business and, although she thinks "Waiter!" is a good film, she is very annoyed with the director. When she agreed to the filming, she wasn't told that the food is disgusting.Although the film might make Jane's restaurant famous if it is a success, she is afraid that people will stop coming because they will think that the food and service is terrible - like it is in the film.Jane is worried she will lose business and may even have to close and start again with a new restaurant.
Having seen the film, i agree that she has a problem. The film company paid her a very small fee and she has since asked for more. The best solution though is for her to contact the newspapers.I am sure they will be interested in her story and it will actually help her business in the end.
