Question

Y=-11x+1 y=-4x+5 найдите координаты точек

Answer 1

Ответ:

Объяснение:

Находим координаты точек пересечения:

$-11x+1=-4x+5; -11x+4x=5-1; -7x=4; x=-\frac{4}{7}; y=-4*-\frac{4}{7}+5=\frac{51}{7}$

Answer 2

To find the coordinates of the points where the two lines intersect, we need to solve the system of equations formed by the two lines. The coordinates of the intersection points represent the values of x and y that satisfy both equations simultaneously.

Let's set the two equations equal to each other and solve for x:

-11x + 1 = -4x + 5

Now, let's solve for x:

-11x + 1 + 4x = 5

Combine the x terms:

-7x + 1 = 5

Now, isolate the x term:

-7x = 5 - 1

-7x = 4

Divide by -7:

x = 4 / (-7)

x = -4/7

Now that we have the value of x, let's find the corresponding y-coordinate using one of the original equations. Let's use the first equation:

y = -11x + 1

y = -11 * (-4/7) + 1

y = 44/7 + 1

y = 44/7 + 7/7

y = (44 + 7) / 7

y = 51 / 7

So, the coordinates of the point where the two lines intersect are (-4/7, 51/7).
