**Algebra 1**

explain: 3x-y=12 4x-5y=16 it is linear equations using substitution method

Thank You, I am just making sure before I turn this in.

Would this be correct? Factpr completley: y^3-12y^2+36y y(y^2-12y+36) y(y-6)^2

**Algebra**

I am wondering if I did this right? Write Using a positive exponets and simplify if possiable. (-3x)^2 I took the -3^2=9 over the x^2 and the answer would be - 9 over x^2

*September 6, 2007*

**Algebra**

I do not understand what I am supposed to do: The problems reads: Evaluate (assume x is not equal to 0). -10x^0 I did this though not sure about it, -10*x^0 -10*1 -10

Ohh, I knew something looked off...so it should be x^2-5x/80-9/20

*August 29, 2007*

**Algebra**

know I am supposed to use the FOIL method.But is this right? I am really not sure I did this right, something just seems off about it. So i would Multiply x/3 * 3x/4=x^2/4 x/3 *-3/5= -x/5 3/4 *3x/4=9x/4 3/4 * -3/5 I know to add both of my bottom numbers have to be the same so...

**Algebra**

How do you Multiply this? (x/3+3/4)(3x/4-3/5)

**Chemical Kinetics**

When experimentally determining the rate law, i am getting a negative fraction. is that right or am i doing something wrong? It is possibly right. I'd have to see you calculations to determine that. It would mean that the reaction is proceeding backwards.

**science**

Does salt water evaporate faster than fresh water? No. The reduction in vapor pressure and evaporaton rate is related to the fraction of the surface that is salt ions instead of water molecules. The Na+ and Cl- ions are not volatile.
