-1/2 - 2/3 - (-1/3)        How do I solve this problem?!?
360833
first remember that -(-x) means +x.\nthe problem is now -1/2 - 2/3 + 1/3\n\nto add or subtract froctions you need a common denominator. so choose 6\nthe proble is now -3/6 - 4/6 + 2/6\n\nadd or subtract the numerators. that answer is -5\nthe answer to this problem is -5/6

Alright, don't listen to the above post...\n\nGrade 12 here, answering questions all day for mere fun.\n\n12)\ny - 3 = -1/3 (x + 4)\n\nEXPLAINED\n\nadd 3 to both sides\ny = -1/3 (x + 4) + 3\n\nexpand 1/3(x + 4) \n= x * 1/3 + 4 * -1/3\n= x/3 + 4/3\ny = -1/3x - 4/3 + 3\n\nTo add -4/3 and 3, use 3 = 9/3\ny = -1/3x - 4/3 + 9/3\ny = -1/3x + 5/3\n\nTrue, my bad. I originally added 4/3 instread of -4/3\n\n\n16)\n(-2, -1) (4, -4)\n\nm = Dy / Dx\nm = ((-1) - (-4)) / ((-2) - (4))\nm = 3 / -6\nm = -1/2\n\ny = mx + b\n(-1) = -1/2(-2) + b\n-1 = 1 + b\n-1 - 1 = b\n-2 = b\n\ny = -1/2x - 2\n\nCHECK\ny = -1/2(4) - 2\ny = -2 - 2\ny = -4\nTherefore it works.\n\n18)\n(0, 0) (2, 3)\n\nm = Dy / Dx\nm = ((3) - (0)) / ((2) - (0))\nm = 3/2\n\nb = 0\n\ny = mx + b\ny = (3/2)x + 0\ny = (3/2)x\n\nNote, the lower post copied my answers

(x^2)/2 - 3(x^(3/2))/(3/2) + c = (x^2)/2 - 2x^(3/2) + c

To do this, you do (2/3) / (1/5). You must flip the denomiator fraction over and change the operation to multiplication. So... that would be (2/3) * (5/1) which would be 10/3.

get a calculator with fraction symbol.\n\n\nfigure out the pattern.\n2/4 = 1/2\n3/6 = 1/2\n4/10 = 2/5

you cannot divide by 0 = a-b\n&#92;

first multiple everythingby x, then simplify and solve:\n\n1/x-2 = 3/x+3 =>\n\nx/x - 2x = 3x/x +3x =>\n\n1 - 2x = 3 + 3x =>\n\n-2  = x

Just multiply:\n(X/3)(3/4 x) -(x/3)(3/5) + (3/4)(3/4x) - (3/4)(3/5)\n\nand simplify from there

so you have (1/2)a+a-(6/3)=4+(1/3)a\n\nadding like terms: (3/2)a-2=4+(1/3)a\n\nsubtract (1/3)a from (3/2)a and add two to both sides:\n(3/2-1/3)a=4+2\n(9/6-2/6)a=6\n(7/6)a=6\n\nnow solve and what do you get? :)

(x - 3/2)(x - 3/2)(x - 3/2) = x³ - (9/2)x² + (9/4)x - 27/8\n(x² - 4x - 3)(x³ - (9/2)x² + (9/4)x + 27/8) = \nx^5 - (17/2)x^4 + (69/4)x³ + (63/8)x² - (81/4)x - 81/8 --- I'd multiply the whole thing by 8 to get rid of all the fractions...\n8x^5 - 68x^4 + 138x³ + 63x² - 162x - 81

Here is how you do it:\n(2,1) and (3,4) = [(2)(3) + (1)(4)]/(2)(1) - (3)(4)\n                        = (6 + 4)/(2-12)\n                        = 10/-10\n                        = -1\n\nTada

Basic subtraction. Ok, you are taking stuff away from what you have, so...\n\n(-3)-3 you have -3 take away three, counting down that is -6. Or you can think of it as the two -s forming a +. \n\n Ok if you have the problem...(-5)-(+3)= change the subtraction sign to + and the 3 to the oppisite in this case -3\n\nExaples\n1. (-8)-+3=   -8+-3 now it is a adding problem = -11

3/x  + 1    the way you put it..

2/x + 3 = 2\n2/x = -1\n-x = 2\nx = -2

just plug -1.5 in for x and see if it equals 1.5.       \n2 X -1.5 = -3                  -3 does not equal 1.5\nso the answer is false
