**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".

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?

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

I think my teacher said that the x could also equal 0 because of the 2...

But I might be wrong.

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...

\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

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...

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...

two-thirds of the way from -11 to 5? How far apart are these two numbers? (Hint: Subtract.) What is one-third of that distance? (Hint: Divide.) What then is two-thirds of the way from the lower number to the higher number? (Hint: Add.) Could you please clarify on the last two steps? Like how to do ...

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? And what is two thirds of the way from -11 and 5? How do you solve someth...
