Okay, one more algebra question, Sorry!?
456859
y = mx + b\n0 = 2m + 4\n2m = -4\nm = (-4/2)\nm = -2\n\ny = -2x + 4\n\nStandard form of this would be \n\n2x + y = 4

simply subtract 7 from both sides. This leave you with\n\nx<_3

We can use faux-algebra to solve these. You probably haven't taken algebra yet. With algebra these would be extremely easy to solve. It's why algebra was invented.\n\na. 16 x ___ has to be -42, because if we add 51 to it we get 9. Thus, ____ has to be -42/16, or -21/8.\n\nb. 2 x ____ has to be 22 - 9 x _____, because if we subtract 8 from it we get 14 - 9 x ____. And 22 has to be 11 x ____, because if we subtract 9 x ____ from it we get 2 x ____. Thus, ____ has to be 22/11, or 2.\n\nc. 9 x ___ has to be 3 x ____ + 3, because if we add 2 to it we get 3 x ___ + 5.  And 3 has to be 6 x ____, becuase if we add 3 x ____ to it we get 9 x ____. Thus, ____ has to be 3/6, or 1/2.\n\nWith algebra, no such thinking would be required. You just plug in the formulas and grind away. You'll see when you study algebra.

= (1 + 8x)*(1 - 8x) = 1 - 64*x^2\n\nAnd what do you say?

by any chance is this a question from your maths homework? lol :D\n\nI cant work it out myself because to put it simple, im crap at maths.

hey this is the math section\nthere is an another section for this type of question\nu had better post it their 4 a better response

Group all elements with y together:\n\ny(x^2 + 6x +9) -x^2 + 2x + 3 = 0\n\nMove the rest to the other side:\n\ny(x+3)^2 = x^2 - 2x + 3 (1)\n\nx = -3 is obviously not the solution of this equation therefore we can divide both sides of (1) by (x+3)^2.\n\n(1) is equivalent to:\n\ny = (x^2 - 2x + 3) / (x+3)^2

The answer is:  4.47, and that's all there is to it!\n\nOk Vanessa, all you have to do is pull up your calculator (Start>Accessories).\nI am not suggesting you don't work it out in your head first: it's just basic. Check the answer on the calc, or, if you get stuck....go back.... to POWERS OF HIGH HOLY ROOTISM   SQUARE YOU KNOW, 1x1+(2x2)+2+(10-5)/1=       Simple:\n1+4+2+5/1=12

hold on let me look at that for a minute....(dya hate math like this as much as i do?)\n\n(1,4) is one for sure\nyea thats' the only one!!!

I posted these sources earlier to someone else who was looking for math help.\n\nGood Luck!!

Sum of roots = 4, product = -7.\n\nNotice the first answer would give a positive product, so it's ruled out since the product is negative.  One of the others is ruled out too -- I'm sure you can figure out which.\n\nOf the two choices remaining, only one of them could give a positive sum, so it's the answer.\n\nPS  I'm sure you can do it from this, but if not, email h_chalker@yahoo.com.au\n\nPPS  I've just looked at Katya's answer.  She's right, except that it doesn't factorise, so you'd have to fall back on a graphing calculator, but that's unnecessary when you can use the simple logic I've outlined.

4x + 6 is not quite right\nwatch the order of operations and distributive properties\n\nrepost your answer and I'll tell you if you got it\n\n(you didn't think I'd just give up the answer, did you ?)

i'd love to help but i'm having trouble with it myself\n\nuse ur math textbook it will have it unless ur math book say algebra and is red ( that my alg. book and it doesn't help) \n\nSRY good luck

Since you're dividing two monomials with the same base (x), you subtract the exponents so the answer is x^6. \n\nHope this helps ;-)
