Question

Y=2x+5. проходит ли график функции через точку В(23;51)?

Answer 1

Подставляем цифры
51 = 23х2+5
51 = 51.
Ответ : Да.

Answer 2

To check if the point B(23, 51) lies on the graph of the function y = 2x + 5, we can substitute the x-coordinate of B (which is 23) into the equation and see if it gives us the y-coordinate (which is 51).

Let's do the substitution:

y = 2x + 5 y = 2 * 23 + 5 y = 46 + 5 y = 51

As you can see, when x = 23, the value of y is indeed 51, which matches the y-coordinate of point B. Therefore, the point B(23, 51) lies on the graph of the function y = 2x + 5.
