Объяснение:

если что то непонятно пишите

Приложения:

sin162812: объясните пожалуйста, а откуда берутся числа например: 1;-1 или 0;5

sin162812: 1;5*

mariakruychkova5: смотрите . все просто . чтобы нарисовать чертеж нужны точки . но первое что мы делаем это находим ооф(область определия функции)то есть то что нельзя брать . в данных случиях можно брать любые числа . для того чтобы провести линию нужны 2 точки . и поэтому мы берем какое нибудь простое число например 0 или 1 и представляем в функцию , вместо (x) и решаем , а то что получилось мы пишем к (y) и в итоги у нас получается координата по которой мы находим точку . тоже самое и со второй точкой

mariakruychkova5: *подставляем в

mariakruychkova5: надеюсь понятно ))

Read Pamela’s speaking about her part-time job and then decide if the facts below are True (T) or False (F).

I had this part-time job of baby-sitting. I worked on Wednesdays, from eight in the morning until two in the afternoon. I only had one little boy, and he was about four at the time. Andy was usually in bed when I got there in the mornings. He woke up around 9. Then after breakfast we went out round the park, then we went back and had a sleep. When he got up we just read baby books. It was a good job. I got good play. I think it was 75 dollars an hour, which wasn’t bad. I really enjoyed it. I liked Andy and he liked me.
