x(x+5) = 2y-6 x(x)+5x = 2y-6 x(x)+5x = 2(6x-32)-6 x(x)+5x = 12x-64-6 x(x)+5x = 12x-58 x(x) = 7x-58 x(x)-7x = -58 x(x)+x = 58/7 This is as far as I've gotten. Never dealt with x squared this year, I don't even think it's part of algebra 1. _________________ Is this the real life? Is this just fantasy? |

x(x+5) = 2y - 6 x^2 + 5x = 2y - 6 / y= 2(6x-32) x^2 + 5x = 12x - 64 - 6 x^2 + 5x = 12x - 70 x^2 + 5x -5x = 12x - 70 -5x x^2 = 7x - 70 x^2 -7x = 7x - 70 -7x x^2 - 7x = -70 Edit: -->: x^2 + x = 10 As far as I got according to what they taught me so far. _________________  Once upon a time...

Hmm i got as far as this:
x(x+5)=2y-6 y=6x-32 x^2+5x=2y-6 x^2+5x=2(6x-32)-6 x^2+5x=12x-64-6 x^2+5X=12x-70 x^2-7x=-70 x^3=10 x=10cubic root ? _________________  |

Wow, alright. I'll ease up on you guys, a bit.
2(x+5) = 2y - 6 y = 6x - 32 There. That should be much easier. By the way, x times x is x squared and it is part of Algebra 1. _________________  "What if there is no tomorrow? There wasn't one today." ~Phil Conners, Channel 9 Pittsburgh Weather Man~

yup i got it right!
K here it is (it's very easy): y=3x/4+10 4x+3y=30 How many solutions does this linear equation have? _________________ |

15 does not equal 26. Try again.

I re-did it and still got it right...
here's my work: x=8 y=16 2(8+5)=2(16)-6 2(13)=32-6 26=26 Makes perfect sense to me... _________________ |

infinite Ok, how's this (btw, I don't know what Algebra 1 is but stuff it, go learn algebra 10 (or whatever the highest is) and don't complain) Simplify ((2x+y)/(x-3)+(x-y)/(x+3)-(3x+2y)/(x^2+x-6))^2=4 then find the relationship between x and y _________________  Last edited by Gold on Mon Feb 08, 2010 1:04 am, edited 1 time in total. |
