First, the slope is (delta y)/(delta X) = (-3)/2) = -3/2\n\nthe y intercept is +6  (interpolating back from \n(6,-3) ,(4,0),(2,3), (0,6)\n\nso the equation is Y=-3/2 X + 6\n\ngo from there and you have your answer.

Solve for y:\n6y=-x+3,\ny=-(1/6)x +(1/2)\nThe coefficient of x is the slope and the othe rterm is the\ny-intercept. So the slope here is -1/6 and the y-intercept is\n1/2.

if y = 6-x\nthen you just put that in for y\n2x-3(6-x) = -2\n2x- 18 + 3x = -2\n5x - 18 = -2\n5x = -20\nx = -4

x^2-3x-18=0\n(x-6)(x+3)=0\nx=6\nx=-3\n6-3=3\n\n2) 3 is correct.

2(y-3) = y-6\n\nThis is what you are supposed to calculate : a value for the y, such that the equation holds.\n\nfor instance try y = 1\n\n2(1-3) = 1-6\n2 - 6 = 1- 6\nand you see that this is not so, thus y=1 is not a solution.\n\nthe standard way to solve is : move all y''s to the left of the=, and all numbers to the right of the =\n\n2(y-3) = y - 6\n2y - 6 = y - 6\n2y -y - 6 = -6 ( move left y to the right, sign changes )\n2y - y = -6 + 6 moved left -6 to right, change sign\n\ny = 0. ( adding the 2y - y together, and the -6 + 6\n\nso the solution is y = o

y = |x|   :   x = 0\n\ny = |x| +2   : x = 0\nor\ny = |x + 2|  :  x = -2\n\ny = |x - 3| + 2   :   x = 3

y'=-x^(-1/2)\ny"=(-1/2)x^(-3/2)\n2x^2[(-1/2)x^(-3/2)]+3x[x^(-1/2)]-x^(-1)=0\n-x^(1/2)+3x^(1/2)-1/x=0\n2x^(1/2)-1/x=0\n2x(x^(1/2))-1=0\nx^(3/2)=-1/2\nx=(-1/2)^(2/3)\n\n\ni think thats correct... but who knows...>.<;;;\nis there an answer key???

Let say x is y, to avoid any confusion.\n3/y = (y + 5)/2\n\nMultiply by 2 at both side.\n3/y x 2 = (y + 5)/2 x 2\n6/y = y + 5\n\nMultiply by y at both side.\n6/y x y = y x (y + 5)\n6 = y(y + 5)\n6 = y^2 + 5y\n\nBring all the numbers to one side.\ny^2 + 5y - 6 = 0\n\nFactorize the equation.\n(y + 6)(y - 1) = 0\n\nTherefore,\ny + 6 = 0  or  y - 1 = 0\ny = -6  or  y = 1\n\nIn short,\ny = -6, 1\n\nAs I had mentioned earlier, x = y.  \nTherefore, x = -6, 1.

1. y = 1/4 - 3\n   y = -2.75\n\ncannot do with multiple domains because there\nis no x value\n\n2. 2y - x = 6\n\na. -8 - x = 6\n      - x = 14\n        x = -7\n\nb. -6 - x = 6\n      - x = 12\n        x = -6\n\nc.  2 - x = 6\n      - x = 4\n        x = -4\n\nd. 12 - x = 6\n      - x = -6\n        x = 6\n\ne. 14 - x = 6\n      - x = -8\n        x = 8

x+y = -1\n2x-y=32\n3x = 31\nx = 10  1/3\ny= -11 1/3\n\nThis is a good place to get lots of answers!

If y = -5 + 3,  then y = -2 and the rest is easy, but when you started to solve it, you were working off of y = -5x +3.\n\nIf it is y = -5 + 3, then y = -2 and x = 1.1\n\nIf it is y = -5x +3, then the next step is to either check the original problem for where you misread it or write null set as the answer.  6 does not equal 7 hence the correct values for x and y are not real numbers...

Y=x^3(x+2)(3x-1)\n we have three possibility for x\nx^3=0 than X=0\nx+2=0 than X=-2\n3x-1=0 than x=1/3\n\nso the answer is a

1.y+2\n2. x+3\n3. z+6\n4. i wasnt sure what it was equal to, so i assued 0... making the answer (x+2)(x+5) however,if it is x2+7x=10...then this answer's wrong...

3x = 2y + 6\nx = (2y + 6) / 3

its:\n\n2 - y / 6 = 8x\n6 (2 - y / 6 = 8x)\n2- y = 48x\n- y = 48x - 2\n-1 (- y = 48x - 2)\n\ny = - 48x + 2\n\nGoodluck!~\n\nI hope you undestand it too...just copying down answers won't help you...
