How many solution sets do systems of linear inequalities have? Do solutions to systems of linear inequalities need to satisfy both inequalities? In what case might they not?

It can have none, one, or infinitely many. Here's a system with no solutions: x 5. Here's a system with one solution: x =3. [ ( = mean "less than or equal" and "greater than or equal") And here's a system with infinitely many solutions: x < 3 and x < 2. In order to satisfy both inequalities, a number must be in both solution sets. ]

State one advantage that the method of substitution has over the intersection-of-graph method.

Weegy: In case the solutions are not perfect integers you make get more approximate value in substitution method then the intersection of graph method (More)

When applying the method of substitution, how do you know that there are no solutions?

Weegy: If while solving a system of equations we get an inequality like
1=0
Since 1 is not equal to 0 the right side of the equation we can conclude the system of equations has no solution User: When applying the method of substitution, how do you know that there are infinitely many solutions? Weegy: We get to know that the system of equations has infinitely many solutions when the system deduces to an eqwuality like
0=0
Then we have infinite ... (More)

can you provide an example that uses the substitution method to solve two linear equations.

Weegy: The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, [ "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable. Here is how it works. (I'll use the same systems as were in a previous page.)
Solve the following system by ... (More)

How might you explain your answer toequations to someone who has not learned algebra?

Weegy: I would need to start to explain to him the basics of Algebra. I would teach it the way how I understood it and using simple terms that he could easily comprehend.
I will provide lots of examples and make him try to answer them. [ [
Students learn best when examples are presented one by one, with increasing complexity. The first Algebra example problem that you work should be extremely simple so that every single student in the room ... (More)
