Re: MathCan you show me how you would solve this? I have the answers is you want to see them #77 20130920 00:39:40
Re: MathStart by doing the subtraction on the left side. Now cross multiply. Factor, You have x = 0 and x = 2. We reject the 0 solution so x = 2. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #81 20130920 02:00:42
Re: MathIn post #77 I solved it already, the answer is 2. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Mathok youre right I see It now what abou the next one Last edited by Derick Mixon (20130920 02:04:48) #83 20130920 02:04:54
Re: MathGive me some time to do the other ones. I will post them right here. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #85 20130920 02:40:41
Re: MathMultiply both sides by 20. Clean it up. Add 8 to both sides. Subtract 5x from both sides. Divide both sides by 15 and you get x =  ( 17 / 15). In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #87 20130920 07:45:36
Re: MathTimes both sides by 24. Add 9 to both sides. Subtract 8x from both sides. x = 1 In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #91 20130920 22:40:34
Re: MathTake 1 / 9 away from both sides. Flip them both, x = 3 For the last one: Times both sides by 15x. Divide both sides 4. x = ( 14 / 4 ) = ( 7 / 2 ) In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #94 20130922 03:45:47
Re: MathState the domain of y = x2 #100 20130924 06:26:49
Re: Math
I get the domain as R and the range as [0,∞)
Domain is R and the range is all positive reals greater than or equal to 2. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
