under what conditions would you use graphing?

Weegy: Market research is all about statistics. A common type of graph that market researchers use is a scatter plot. This type of graph is made after a test is done on a group of people. [ For example, a group of people may be asked to take a quiz that will test their knowledge of recycling in the United States. By plotting the scores of these test takers on a coordinate plane, researchers can study how much people know about recycling and ... (More)

Under what conditions would you use Elimination? Substitution?

Weegy: The linear equations of one variable does not require substitution or elimination. We solve linear equation of one variable and one single equation by isolation of the unknown or variable to one side and knowns or numbers to the other side. [ The type of operations we do is (i) adding or subtracting equals to both sides, (ii) multiplying or dividing both sides by equals. But never multiply or divide by zeros thinking that zeros are ...

In solving a system of two linear equations or two functions by graphing what is meant by if the system is consistent or inconsistent? Please show me how to solve.

Weegy: Linear Simultaneous Equations with Two Variables
In the previous module, linear equations with two variables were discussed. [ A single linear equation having two unknown variables is practically insufficient to solve or even narrow down the solutions for the two variables, although it does establish a relationship between them. The relationship is shown graphically as a line. Another linear equation with the same two variables may be ... (More)

In solving a system of two linear equations or two functions by graphing what is meant by if the equations in a system are dependent or independent?

Weegy: If the graph of the equations intersects each other at a point, then ordered pair corresponding to the point of intersection will be the solution to that system. [ In this case, the system will have exactly one solution.
If a system has exactly one solution, then the equations are said to be independent.
If the graph of the equations coincides, then all the points on the line will be the solution to that system. In this case, the ... (More)
