Question

График уравнения 5x-6y=7 проходит через точку A(-a;3a).определите значение x и y. Помогите

Answer 1

Точка А (-a; 3a), т.е. она имеет координаты:
х=-a, y=3a
подставим значения в исходное уравнение, чтобы определить значения (х,y):
5x - 6y = 7
-5a - 18a = 7
-23a = 7
a = -7/23
т.к x = -a и y = 3a, тогда х=7/23, а у=-21/23

Answer 2

Подставим точку в уравнение функции:
x = -a
y = 3a
5x - 6y = 7
-5a - 18a = 7
-23a = 7
a = -7/23

x = -a = 7/23
y = 3a = -21/23

Answer 3

Problem Analysis

We are given the equation of a line, 5x - 6y = 7, and we need to determine the values of x and y when the line passes through the point A(-a, 3a). To solve this problem, we can substitute the coordinates of point A into the equation and solve for x and y.

Substituting the Coordinates of Point A

Let's substitute the coordinates of point A(-a, 3a) into the equation 5x - 6y = 7:

5(-a) - 6(3a) = 7

Simplifying the equation:

-5a - 18a = 7

-23a = 7

To find the value of a, we can divide both sides of the equation by -23:

a = -7/23

Finding the Values of x and y

Now that we have the value of a, we can substitute it back into the coordinates of point A to find the values of x and y:

x = -a = -(-7/23) = 7/23

y = 3a = 3(-7/23) = -21/23

Therefore, the values of x and y when the line 5x - 6y = 7 passes through the point A(-a, 3a) are x = 7/23 and y = -21/23.

Answer

The values of x and y when the line 5x - 6y = 7 passes through the point A(-a, 3a) are x = 7/23 and y = -21/23.
