Equation 1: y = 8/x => xy = 8
Equation 2: y = 7+x
Substitute Equation 2 into Equation 1:
x(7+x) = 8
x2+7x-8 = 0 => (x-1)(x+8) = 0
x = 1 or x = -8
Substitute these values into Equation 2:
When x = 1, y = 8
When x = -8, y = -1
The coordinates are (-8,-1) and (1,8)
They work out as: (-3, 1) and (2, -14)
The points of intersection are: (7/3, 1/3) and (3, 1)
Equations: x -y = 2 and x^2 -4y^2 = 5 By combining the equations into a single quadratic equation in terms of y and solving it: y = 1/3 or y = 1 By means of substitution the points of intersection are at: (7/3, 1/3) and (3, 1)
A secant is a line that intersects a curve at two or more points. In the context of a circle, a secant can be defined as a line that crosses the circle, providing two points of intersection. These intersection points help in calculating various properties of the circle, such as angles and lengths, depending on the specific geometric scenario involved.
Where two surfaces intersect, a line or curve is formed, depending on the nature of the surfaces. In three-dimensional geometry, the intersection can be a line if both surfaces are planes, or a curve if one or both surfaces are curved. This intersection represents all the points that are common to both surfaces. The specific characteristics of the intersection depend on the equations defining the surfaces involved.
They work out as: (-3, 1) and (2, -14)

The intersection of the individual graphs. In the simplest case, the graph for each equation consists of a line (or some curve); the intersection is the points where the lines or curves meet.

If: x-2y = 1 and 3xy-y2 = 8 Then: x =1+2y and so 3(1+2y)y-y2 = 8 => 3y+5y2-8 = 0 Solving the quadratic equation: y = 1 or y = -8/5 Points of intersection by substitution: (3, 1) and (-11/5, -8/5)

YES. The intersection of two planes always makes a line. A line is at least two points.
If: y = 10x -12 and y = x^2 +20x +12 Then: x^2 +20x +12 = 10x -12 Transposing terms: x^2 +10x +24 = 0 Factorizing: (x+6)(x+4) = 0 => x = -6 or x = -4 Points of intersection by substitution are at: (-6, -72) and (-4, -52)
