### How to tell if a system of equations has no solution or infinitely many

The two equations are equivalent and also second equation can be obtained from the first by multiplying the first equation by 2 and vice versa. For example, as three parallel planes do not have a common point, the solution set of their equations is empty; the solution set of the equations of three planes intersecting at a point is single point; if three planes pass through two points, their equations have at least two common solutions; in fact the solution set is infinite and consists in all the line passing through these points. Determine whether a solution reveals that a system has one, many, or no solutions Interpret the solution to a system of equations that represents profits for a business Now that we have several methods for solving systems of equations, we can use the methods to identify inconsistent systems. The graphs of the equations in this example are shown below. The set of all possible solutions is called the solution set. In the next example, we determine how many different types of tickets are sold given information about the total revenue and amount of tickets sold to an event. The point at which the two lines intersect is called the break-even point. If you look at the condition for infinite solution it can clearly be seen that the system given is of equivalent equations.

Infinite solution Infinite solution The meaning of Infinite is countless, so many that it cannot be counted. Therefore, the lines are parallel and do not intersect. How many children and how many adults bought tickets?

## How to determine the number of solutions in a system of equations

Parallel lines will never intersect; thus, the two lines have no points in common. For linear equations, logical independence is the same as linear independence. A linear equation always represents a straight line. Determine whether a solution reveals that a system has one, many, or no solutions Interpret the solution to a system of equations that represents profits for a business Now that we have several methods for solving systems of equations, we can use the methods to identify inconsistent systems. This means we can deduce one equation from other either by dividing or by multiplying it by a certain number. The system is said to be consistent and also dependent. For example, the equations. How many children and how many adults bought tickets? The solution set is the intersection of these hyperplanes, and is a flat , which may have any dimension lower than n. Why would we write the solution this way? Identify the input and output of each linear model. The point at which the two lines intersect is called the break-even point.

It tells us that x can be anything, x is x. This illustrates that the break-even point for businesses occurs when the profit function is 0. The set of all possible solutions is called the solution set. Notice the results are the same.

Notice the results are the same. Try It Solve the following system of equations in two variables. A linear system may behave in any one of three possible ways: The system has infinitely many solutions. Infinite Solutions for Linear Equations The linear equations are defined as the algebraic equations that have only first powers of variables. Identify the input and output of each linear model. Example 1: For what value of m the given system has infinite solutions. Clearly, knowing the quantity for which the cost equals the revenue is of great importance to businesses. The x-axis represents quantity in hundreds of units. In general, a system with the same number of equations and unknowns has a single unique solution.

Why would we write the solution this way? There are different cases to check for infinite solution condition. Show Solution children, adults Sometimes, a system of equations can inform a decision. In this case everything is a first degree so we are dealing with a plane so we actually have here is three planes and we need to figure out how three planes can intersect okay?

The third system has no solutions, since the three lines share no common point. The revenue function is shown in orange in the graph below. A linear equation always represents a straight line. Dependent systems have an infinite number of solutions because all of the points on one line are also on the other line. It is an inconsistent system. In the next example, we determine how many different types of tickets are sold given information about the total revenue and amount of tickets sold to an event. Identify the input and output of each linear model. Show Solution children, adults Sometimes, a system of equations can inform a decision. Because we have two companies to consider, we will define two functions.

The shaded region to the right of the break-even point represents quantities for which the company makes a profit. Also, it is important to see that in this system all values of right hand side in all three equations is the same. Rated 10/10 based on 110 review
