How do you approximate real solutions in algebra? Regarding algebra, Solution to Algebra Problems are not always accurate. Sometimes you also get approximate solutions to the problems. In that case what you can do is explaine…d below: If you solve and equation and you end up with some obscure number with loads of decimal places on your calculator then writing them all down probably isn't a good idea.
Sometimes by doing a sum on a calculator you can make something even less accurate. It is perfectly acceptable to give and answer as a square root or with constants such as pi in them.
Just make sure that it is as simple as you can make it. So if you can do the question on paper and move numbers around by hand then you should. If however you have to do it on a calculator then just remember that your output cannot be more precise than your input. What is the mean in algebra?
In math in general MEAN means average. Mean has no negative connotation in Math. By the w…ay, in Algebra, two wrongs do make a right- a Negative times a Negative produce a positive product. In algebra is it possible to have no solution? It is definatly possible to have a no solution answer in algebra.
The most common time a no solution answer will occur is in an absolute value problem. Absolute value problems… cannot equal zero so if you have the problem:Procedure: To solve equations involving absolute values of variable expressions, it is necessary to solve the two equations which naturally result from the definition of absolute value.
The solution set contains the solution set of the original equation. The absolute value equation means that b is the difference between the unknown number x and the fixed value a. For example, means the difference between x and 7 is 3. On a number line, that means the two solutions to the equation are the two numbers that are a distance 3, in either direction, from 7.
Section 1 – 5: Solving Absolute Value Equations Step 1: Get the absolute value expression alone on one side of the equation. Step 2: If the absolute value expression is alone and is equal to a negative number STOP.
There is no solution. Write NS or use € ∅the symbol. Step 3: If the absolute value expression is alone and is equal to a positive number then.
Equations That have Absolute Value Signs on Both Sides. If we have absolute value signs on both sides of the equation, we can play the same game with two choices as follows.
Your Turn Isolate the absolute value expression in each equation to determine if the equation can be solved.
If so, finish the solution. If not, write "no solution.". The first six problems ask students to solve absolute value inequalities of varying difficulty. The next two problems provide modeling opportunities. The final question ask student to describe what the graph of an absolute value equation with one real solution and one extraneous solution would .
