3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
3x + y = -4 -3x -3x y = - 4 -3x now plug in points!+++To clarify the principle, re-arrange the equation so it reads as "y = [something done to x]" then calculate a table of points for the plot itself.
This is a quadratic equation requiring the values of x to be found. Rearrange the equation in the form of: -3x2-4x+6 = 0 Use the quadratic equation formula to factorise the equation: (-3x+2.69041576)(x+2.23013857) Therefore the values of x are 0.8968052533 or - 2.230138587 An even more accurate answer can be found by using surds instead of decimals.
3x-2y+12 = 0 Rearrange the equation in the form of y = mx+c: y = 1.5x+6 Therefore the slope is 1.5 and the y intercept is 6
3x + 2y = 8 This is an equation. It could be the equation of a line.
(52/11, 101/11) and (-2, -11) Rearrange 3x-y = 5 into y = 3x-5 and substitute this into the curve equation and then use the quadratic equation formula to find the values of x which leads to finding the values of y by substituting the values of x into y = 3x-5.
The sum of 3x plus 2 and -4 plus 3 is 3x+1 if the equation is (3x+2)+(-4+3). If they are two separate questions, 3x+2 remains as itself while -4+3=-1.
3x^-2 -3x^2 is not a quadratic equation because it does not take the form ax^2 +bx+c.
-7
The answer has been right under your nose all this time.The equation of y equals -3x isy = -3x
No, an equation needs an "=".
