Tutors Answer Your Questions about absolute-value (FREE)
Question 720177: I'm not sure if this qualifies for absolute value, but here goes. The problem appears in the form: 3 to the left of the lines indicating absolute value, y+3 inside the lines indicating absolute value, and < 9 ot the right of the lines. I believe it should be read 3 times the ablsolute value of y plus three is less than 9, but I'm not sure and I'm not sure of the method to solve. If you can help or refer me to someone who can it would be greatly appreciated. Thank you.

Question 722225: |x√3:(457)+√2:(101)|+ 2√5:(423)=-√5:(423)
IF you don't understand it means absloute value sign cube root of 457 plus square root of 101 plus 2(a qhole number which is outside the sqaure root)5th root of 423 equals - 5th root of 423

Question 723682: 1. The length of a rectangle exceeds 3 times its width by 1 inch. If the length of the rectangle is diminished by 3 inches and the width is doubled, a new rectangle is formed whose perimeter is 46 inches. Find the dimensions of the original rectangle. (Please help, thanks! I don't understand what they meant by 'exceeds' what equation do I do? Please show work and steps!)
2. The length of a rectangle exceeds its width by 4 meters. If the width is doubled and the length is diminished by 2 meters, a new rectangle is formed whose perimeter is 8 meters more than the perimeter of the original rectangle. Find the dimensions of the original rectangle. (Again, please show work and steps. Thanks so much!)

Question 731903: Can someone let me know what is
1+x divided by 1-x greater than equal to to 1
And i need something clearified. When solving absolute values of inequalities when plotting the graph when do u shade in the circle on the graph and when do u plot above the line with th arrows instead of on the line.Thanks!!
