Объяснение:

Щоб знайти паралельну пряму до заданої прямої y = 2x - 3, ми можемо використати властивість паралельних прямих, за якою паралельні прямі мають однаковий нахил.

Отже, щоб знайти паралельну пряму, ми залишаємо вираз для нахилу незмінним і змінюємо тільки точку перетину з віссю ординат (y-перехоплення).

Задавши нове значення y-перехоплення, ми знайдемо рівняння для паралельної прямої.

Наприклад, якщо ми хочемо знайти паралельну пряму, яка проходить через точку (3, 5), ми можемо використати наступне рівняння:

y = 2x + b,

де b - це нове значення y-перехоплення. Рівняння паралельної прямої запишеться як y = 2x + b.

Тепер, враховуючи точку (3, 5), ми можемо підставити значення координат в це рівняння:

5 = 2 * 3 + b,

5 = 6 + b,

b = 5 - 6,

b = -1.

Таким чином, паралельна пряма до y = 2x - 3, яка проходить через точку (3, 5), має рівняння y = 2x - 1.

Read the text about school life in Britain in the early 20th century and tick the things described in the text. Find the sentences and phrases to explain your answers.

сам текст:

When we were old enough to go to school, we walked
there on our own. The school was a stone throw from our
house so we were lucky. Some children had to walk more
than a mile to get there.
The school had three classrooms: one for the young-
est children, one for the middle class and the biggest
room for the oldest children. Mr Thompson, the head-
master, taught the oldest class himself. He was very strict.
We were not allowed to talk. If someone misbehaved,
they had to come out and stand in front of the class. But
if it was really serious, they had to hold out their hand for
the cane. They felt miserable, though it didn't hurt too
much.
There was a wall in the schoolyard which divided it
into two parts. The boys came to school through the
main gate whereas the girls through the garden gate.
It was ridiculous as we studied in the same class but had
to play in separate playgrounds with the wall between us.
In the morning we all came to the big room, sang
a hymn and said a prayer. The youngest children learned
how to write by drawing letters in a sand tray. When they
got older, they used dip pens with ink. I remember learn-
ing poems and tables by heart. Small children worked
with dark-green plasticine and older girls learned to sew
and knit.
In the school there were no lunches so we had to go
home to eat. The children who lived far away brought
their lunches to sch0ol. When it was cold in winter,
Mr Thompson made a hot drink and the children sat
around the coal fire to eat.
