Question

График обратной пропорциональности проходит через точки А(0,6;-8) и В (m;1,2).Найдите значение m. срочноо,прошу,умоляю

Answer 1

Решение такое

прямая пропорциональность - уравнение вида y=ax
подставляем точку С х=2, у=1

1=2а
а=1/2

значит у=1/2*х
Подставляем D
у=м=1/2*(-4)=-2
m=-2

Answer 2

Finding the Value of m in a Graph of Inverse Proportionality

To find the value of m in the graph of inverse proportionality passing through points A(0.6, -8) and B(m, 1.2), we can use the relationship between two variables in inverse proportionality, which can be expressed as:

xy = k

Where k is a constant.

Using the Given Points to Find the Value of m

We can use the given points A(0.6, -8) and B(m, 1.2) to find the value of m.

Using the point A(0.6, -8): - We have: x = 0.6 and y = -8 - Substituting these values into the equation xy = k, we get: 0.6 * (-8) = k - This gives us the value of k.

Using the point B(m, 1.2): - We have: x = m and y = 1.2 - Substituting the value of k obtained earlier into the equation xy = k, we get: m * 1.2 = k - Since k is the same constant for both points, we can equate the two expressions for k.

Solving for the Value of m

By equating the two expressions for k: - 0.6 * (-8) = m * 1.2 - Solving for m, we get: m = (0.6 * (-8)) / 1.2

Calculating the Value of m

Let's calculate the value of m using the given points and the equation derived above.

m = (0.6 * (-8)) / 1.2

m = -4

Therefore, the value of m is -4.

This calculation shows that the value of m in the graph of inverse proportionality passing through points A(0.6, -8) and B(m, 1.2) is -4.
