Question

Постройте графики функций и найдите координаты их точки пересечения y=7x и y=8x-1 Желательно сделать в тетради, а прислать фото

Answer 1

Координат точек ты можешь сделать просто поставив цифры от 1 до 10(к примеру) и нарисовать картину
а точка пересечения 7х=8х-1
-х=-1
х=1
у=7*1=7
(1;7)

Answer 2

Finding the Intersection Points of y=7x and y=8x-1

To find the intersection points of the given functions y=7x and y=8x-1, we can set them equal to each other and solve for the value of x. Let's proceed with this calculation.

First, we set the two equations equal to each other: 7x = 8x - 1

Now, we solve for x: x = 1

So, the x-coordinate of the intersection point is 1.

To find the y-coordinate, we can substitute the value of x into either of the original equations. Let's use y=7x: y = 7(1) = 7

Therefore, the coordinates of the intersection point are (1, 7).

Graphical Representation

I encourage you to plot the functions y=7x and y=8x-1 on a graph to visualize their intersection. Once you've plotted the functions, you can mark the point of intersection at (1, 7) to visually represent the solution.
