Question

Не выполняя построения, найдите координаты точек пересечения графика функции y=-0,7x+14 с осями координат.

Answer 1

Ответ:

x=20

Объяснение:

-0,7x+14=0

-0,7x=-14

x=20

Answer 2

Ответ:

(20;0), (0;14)

Объяснение:

пересечение с Ох:у=0

-0,7х+14=0

-0,7х=-14

х=20

(20;0)

пересечение с Оу:х=0

у=-0,7•0+14=14

(0;14)

Answer 3

Finding the Intersection Points

To find the coordinates of the points where the graph of the function y = -0.7x + 14 intersects the coordinate axes, we can substitute the corresponding values of x and y.

1. Intersection with the x-axis: - When the graph intersects the x-axis, the y-coordinate is 0. - Substituting y = 0 into the equation y = -0.7x + 14, we get: 0 = -0.7x + 14 - Solving for x: -0.7x = -14 x = -14 / -0.7 x = 20

Therefore, the point of intersection with the x-axis is (20, 0).

2. Intersection with the y-axis: - When the graph intersects the y-axis, the x-coordinate is 0. - Substituting x = 0 into the equation y = -0.7x + 14, we get: y = -0.7(0) + 14 y = 14

Therefore, the point of intersection with the y-axis is (0, 14).

So, the coordinates of the points where the graph of the function y = -0.7x + 14 intersects the coordinate axes are: - Intersection with the x-axis: (20, 0) - Intersection with the y-axis: (0, 14)
