постройте график уравнения : х+у=4

Ответы

Автор ответа: GREENDEY

х + у = 4

у = 4 - х

у = - х + 4

Это линейная функция, её график - прямая.
строим прямую по двум точкам. Найдем их координаты и внесём в таблицу :

х 0 4
y 4 0

Далее строишь две точки ( 0 ; 4) и ( 4 ; 0 ) и проводишь через них прямую - это и есть график этой функции.

In the Cave
In the corner we saw three huge stone boxes full of lumps of gold and crudely made coins. (1) There must have been thousands of them, more! We all went over and picked up the metal letting it fall through our fingers, and back into the box.
Suddenly John jumped back. We all looked round to see him struggling with Gagool. “Look out! (2)” John shouted. We all ran over, but before we could help, Gagool made a last effort and freed herself and dived for the door. But she was too late, the heavy stone slab came down on her.
We all tried to lift the stone up. (3) We must have tried for an hour, bul in the end the torches went out, and we were still no closer to moving the heavy stone.
“Why is the air in the cave still fresh after all these hours?” asked Sir Heniy, after several more hours had passed. “(4)”
There was nothing to lose, so we started feeling the walls and floor to see if there were any cracks. (5) After an hour and a half John cried out, “Hold on, I think I have found something. Come here!” With one of our last matches we were able to see a metal ring set into a stone. The air was blowing through the cracks around the edge of the block. (6) When it opened we could see a narrow staircase leading down into the mountain.
Before we went down the stairway we filled our pockets and a couple of sacks with gold. In the darkness we groped our way down the stairs and along a passage.
