3x + 4y = 24  is 4 the x axis and 3 the y axis???

When x=0, that line will cross the y-axis. When y=0, that line will cross the x-axis.

You know that\n              1)3x+4y=12y\n              2)-2x+10=12y\nSo you can substitute 3x+4y for 12y in equation 2. Hence:\n              3)3x+4y=-2x+10\n                   5x=10-4y\n                    x=2-4y/5\nSubstitute this value for x into equation 1 and it becomes:\n              1)8y/5+6=12y\n                     y=15/26\nPlug this back into 3 and you get\n              3)x=2-(4/5)*(15/26)\n                x=20/13\nTherefore the answer to the system is (x,y)=(20/13,15/26)

xy = 4 then y = x/4\n\nx^2 +  4y^2 = 20\nx^2 + 4 x^2/16 = 20\nx^2 + x^2/4 = 20\n4x^2 + x^2 = 80\n5x^2 = 80\nx^2 = 80/5\nx^2 = 16\n\ntherefor\nx = 4\nthen \ny=1

multiply both sides by 3 and you'll get\n3x-3*4=-2*(y-9)\n\n3x-12=-2y+18\n-2y+18=3x-12\n-2y=3x-12-18\n-2y=3x-30  divide both sides by -2\n\ny = (-3/2)x + 15

6x - 2y = 8 dividing both sides by 2 we get => 3x - y = 4 -----(1)\n3x + 7y = - 4 -----(2)\n(1) - (2) => 3x - y - 3x - 7y = 4 - (-4)\n-8y = 8 and y= -1\nso x = 1

you would take the 2x-4y=3 and solve for a variable, such as x=(3-4y)/3   you now have what x equals and you sub that into the other equation so you now have 2[(3-4y)/3]-3y=0 and you should be able to solve that equation

2x - 4y = 24 Divide both sides by 2\n-x + 5y = -24\n\nx - 2y = 12 (1)\n-x + 5y = -24 (2)\n\nAdd (1) and (2) together\n(x-2y) + (-x + 5y) = 12 - 24 <=> 3y = -12 <=> y = -4\n\nSubstitute y = -4 in (1) => x -2.(-4)= 12 <=> x + 8 = 12 <=> x = 12 - 8 =4\n\nx = 4\ny = -4\n\nWhat do you mean by graphical solution? You can draw the two lines and see the co-ordinate of the intersection, I guess. (?)

y = 3x^2 + 12x - 7\nWhat do the directions say?

1. y-axis\n\n2. 2nd quadrant\n\n3. 2nd or 3rd quadrants\n\n4. 2x + 3y = 6 => y = 2 - (2/3)x\n\n5. x - 2y = 8 => y = (1/2)x - 4\n\n6. x - 3y = 4 => x = 4 + 3y\n   Only (a) is a solution\n\n7. y - 2x = -1 => y = -1 + 2x\n   (b), (c) are solutions

i think you wrote it down wrong, maybe it should just be 3x+4y=12 and then you solve for y.\n\nalso, i don't know what an in and out table is
