Absolute Values of Products in Open Sentences

Solve each open sentece and graph its solution set.


I solved and got , then I split it into two equations
got me
got me
The only problem is, I can't tell how it's "no solution".

Re:

I think my teacher said that the x could also equal 0 because of the 2... :confused: But I might be wrong. :oops: If you had a factor of just "x", then "x = 0" would be another solution (because you'd set the factor, x, equal to zero). But the process doesn't work with plain num...

Um... what about it? :confused:


So x=11,13 is right? Would the 2 outside the parentheses have anything to do with the answer?

Word Problem

The sum of the reciprocals of 2 consecutive even integers is \frac {5}{12} . Find the integers. Would the equation be \frac {1}{2x}+\frac{1}{2x+2}=\frac{5}{12} ? And how exactly would it be solved? The sum of two integers is 24 and the sum of their square is 290. Find the two integers. Is the equat...

Re: algebra: t^2(t^5)/(t^3)^2 (how do i solve this)

\frac{t^2(t^5)}{(t^3)^2} First multiply the numerator. So multiply t^2(t^5) . Then solve the denominator. Put the result of t^2(t^5) on the top and the result of (t^3)^2 on the bottom. After all of this, divide t^2(t^5) and (t^3)^2 . :D

solving absolute-value inequality: 3 - 2|4 - 3(2x - 1)| > -2

How would you solve a problem like this: 3-2|4-3(2x-1)|>-2 I did this, but I am not sure if it's correct. 3-2|4-6x-3|>-2 -2|4-6x-3|>-5 |-8+12x+6|>-5 I just want to know the steps. To stapel_eliz: Is there a lesson like this in the Purplemath site? Simplify: \frac{1-xy^{-1}}{x^{-1}-y^{-1}} My...

Re: Factoring and Simplifying

I suspect that you're supposed to note that: . . . . . a^2\, -\, b^2\, +\, 6b\, -\, 9\, =\, a^2\, -\, \left(b^2\, -\, 6b\, +\, 9\right) Then convert the parenthetical into its squared-binomial form: . . . . . a^2\, -\, (b\, -\, 3)^2 ...and then factor the difference of squares. Simp...

Factoring and Simplifying

Factoring harder problems: a 2 -b 2 +6b-9 Am I just supposed to factor the "-b 2 +6b-9" part? (a+2b) 3 -8 Do I have to multiply the (a+2b) 3 part? Then factor it with the -8? Simplifying: The link is my problem: http://mathway.com/math_image.aspx?p=(SMB02FSMB03aSMB02ESMB032SMB02eSMB03-xSMB...

Natural numbers can't be negative, so how do you solve something like this: {the natural numbers between -5 and 4} Would it be no solution or something? :confused: What is the equation for: two-thirds of the way from -11 to 5?
