### Absolute Values of Products in Open Sentences

Solve each open sentece and graph its solution set.

$5-4|2-3t|>21$
I solved and got $|2-3t|<-4$, then I split it into two equations
$2-3t<-4$ got me $t>2$
$2-3t>4$ got me $t<$$\frac{2}{3}$
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 numbers, because "2 = 0...

### Re:

But what about the 2 outside the parentheses?
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.

### 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 $(t^3)^2$.

### 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 teacher...

### 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. Simplify the two res...

### 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?

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?
