write an absolute value epuation that has 2 and 6 as solutions
Welcome to OpenStudy, @brenna00 ! If you have any questions about the site and how to get around it, don't hesitate to ask. First things first for this question: Do you know what an absolute value is?
well I know what one looks like but I don't know the definition
basically it means that instead of looking at it as positive or negative, you look at how far AWAY it is from 0. So the absolute value of -3 is just 3. Does that make sense?
yes
So if you apply that to equations, it would be like this: \[\left| x-10 \right| =6\] Solution 1: x-10=6, so x=16 Solution 2: x-10 = -6, so x =4 The two solutions in that case are 4 and 16. In this case, you need to find two equations whose solutions are 2 and 6.
(basically you take the absolute value expression and set it equal to a negative number and a positive number, and it gives you two different answers)
That's fair ;) Let me see if i can help
How about \[\left| x-4 \right| = 2\] ? Would that work?
yes it works
thank you
no problem! :)
