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)

Where are solutions to a system seen on the graph?

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.


What are the points of intersection between the line x -y equals 2 and the curve x2 -4y2 equals 5?

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)


Segments below is a secant?

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.

Does intersection of 2 planes always contain at least 2 points?

YES. The intersection of two planes always makes a line. A line is at least two points.


What are the points of intersection of the line of x -2y equals 1 with the curve of 3xy -y squared equals 8 showing work?

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)

What is a straight line that intersects a curve?

A straight line that intersects a circle or curve at two points, but which has both end points outside the circle or curve is called a secant. A straight line that links two points on a circle or curve is called a chord. A straight line which touches a circle or curve at one point is called a tangent. A straight line that cuts a circle or curve at one point is a straight line.* For moving diagrams see Related links below this box.


What are the points of intersection when the line y equals 10x -12 crosses the curve y equals x squared plus 20x plus 12?

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)
