## How do you find the ordered pair of a function?

How do you figure out if a relation is a function? You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!

## Is there an ordered pair that is a solution to both of these linear equations?

Is there an ordered pair that is a solution to the linear equations describing BOTH of these lines? Yes. The ordered pair \$\$ −4,1 is on both lines.

## How do you find the solution to a system of equations?

To check a system of equations by substitution, you plug your values for x and y into the original equations. If both simplified expressions are true then your answer is correct. Since x=2 and y=−3 worked for both equations I know that (2,−3) is the solution to this system of equations.

## How do you solve for two variables in an equation?

In a two-variable problem rewrite the equations so that when the equations are added, one of the variables is eliminated, and then solve for the remaining variable. Step 1: Multiply equation (1) by -5 and add it to equation (2) to form equation (3) with just one variable.

## How do you plot ordered pairs?

A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.

## How do you determine whether a point is a function?

You can tell whether a relation is a function by plotting the numbers on a graph and applying the vertical line test. If no vertical line passing through the graph intersects it at more than one point, the relation is a function.

## How do you find a function?

When we have a function in formula form, it is usually a simple matter to evaluate the function. For example, the function f(x)=5−3×2 f ( x ) = 5 − 3 x 2 can be evaluated by squaring the input value, multiplying by 3, and then subtracting the product from 5.

## How do you find the ordered pair solution of a linear equation in two variables?

Step 1: Graph the first equation. Step 2: Graph the second equation on the same coordinate system as the first. Step 3: Find the solution. Step 4: Check the proposed ordered pair solution in BOTH equations. Step 1: Graph the first equation.Step 2: Graph the second equation on the same coordinate system as the first.

## What do you mean by ordered pair?

In mathematics, an ordered pair (a, b) is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair (a, b) is different from the ordered pair (b, a) unless a = b. (In contrast, the unordered pair {a, b} equals the unordered pair {b, a}.)

## What is the solution to that system?

If you have a system of equations that contains two equations with the same two unknown variables, then the solution to that system is the ordered pair that makes both equations true at the same time.

## What are the 3 methods for solving systems of equations?

There are three ways to solve systems of linear equations in two variables: graphing. substitution method. elimination method.

## What are the three possible solutions to a system of equations?

There are three possible outcomes for a system of linear equations: one unique solution, infinitely many solutions, and no solution. This video shows an example of each type of outcome.

#### H2o2 decomposition equation

What does h2o2 decompose into? Hydrogen peroxide can easily break down, or decompose, into water and oxygen by breaking up into two very reactive parts – either 2OHs or an H and HO2: If there are no other molecules to react with, the parts will form water and oxygen gas as these are more stable […]
