A point with an ordinate -1.3 belongs to the graph of the equation x-xy=46. Find the abscissa of this point.
We know that the point (x, -1.3) satisfies the equation x-xy=46. Substituting -1.3 for y, we get:
x - x(-1.3) = 46
Simplifying:
x + 1.3x = 46
2.3x = 46
x = 20
Therefore, the abscissa of the given point is 20.
To find the abscissa of the point with an ordinate -1.3 that belongs to the graph of the equation x - xy = 46, we can substitute the given ordinate value into the equation and solve for the abscissa.
Given equation: x - xy = 46
Let's substitute y = -1.3 into the equation:
x - x(-1.3) = 46
Simplifying the equation:
x + 1.3x = 46
Combining like terms:
2.3x = 46
Dividing both sides by 2.3:
x = 46 / 2.3
Calculating the result:
x = 20
Therefore, the abscissa of the point with an ordinate -1.3 on the graph of the equation x - xy = 46 is 20.
