Homework Help: Algebra 2

Posted by Caroline on Wednesday, September 19, 2012 at 9:11pm.

Absolute Value Equations
Will someone please check to see if I am doing this correct?

1.|7x+2|=10
x= (8/7) or (-12/7)
2.|3x-5|=-1
I got "no solution" because "d" cannot be negative.
3.|x^2-2x-16|=8
x= 6,-4 or x=4,-2
4.|3x-2|=7
x= 3 or (-5/3)
5.|x^2+2x+1|=-4
I got "no solution" because "d" cannot be negative.
6.|3x+2|+3=0
|3x+2|=-3
Again, I got "no solution" because "d" cannot be negative.


These I don't understand how to do.

7.|3x-1|=|x+4|
8.|(3)/(k-1)|=4
