Plz help, how do u solve this equation???

You have to use the Pythagorean Theorem.  It says the lengths of the two short sides of a right triangle squared, then added together, equal the length of the long side squared.  Picture a triangle on your sheet of graph paper.  One leg goes from point P straight left to 2,4.  The second goes from 2,4 straight down to Q.  The third connects P and Q and is the longest of the three legs.  The length of the first leg is 2.  The length of the second is 5 (or -5 if you like; it doesn't matter since we're fixing to square it).  The lengths squared are 25 and 4.  So the distance between P and Q squared is 29.  The distance is root(29), which is 5.385.  That's your answer.

Use the following equation and solve:\n\nP1V1/T1=P2V2/T2\n\nT2=P2V2T1/P1V1\n\nalso note the significant figures!!!!

Step 1: Solve one equation for one variable in terms of the other.\nStep 2: Plug that into the other equation and solve for the second variable.\nStep 3: Plug the second variable into the first equation and solve for the first variable.

honestly....good luck\n\ntry www.mathworld.com\n\ndo a search for differential equations, i think that would be your best bet...but that can get confusing...good luck

You can't, algebraically.  You have two equations and three variables.  Sorry.  You need one more equation, such as a = b.

write them so they can be added top to bottom (i.e. line up the x's, y's, and constants):\n\n4x + 2y = -4\nx - 2y = -3  (we need to rearrange the original equation here to line things up)\n\nnow add top to bottom:\n\n(4x)+(x)  +  (2y)+(-2y)  =  (-4)+(-3)\n5x + 0 = -7\n5x = -7\nx = -7/5\n\nnow plug x in to either equation to solve for y:\n\n2y = -7/5 + 3\n2y = -22/3\ny = -22/6 = -11/3\n\nHope this helps :)

If u could give the entire question i could solve it for u and i'm not jokin. its actually quite easy.Its basically\n\n(w+3)/4w * 2w/(w-3).So wat ud have is\n\n1/2( (w+3)/(w-3) )\n\nits xactly like sayin 2/4 = (2/1) / (4/1)

give parameters for x, y, and z.  Otherwise you cannot prove it, as no parameters are given for the equation as you described it.
