How do you solve -12x equals 6y?
its just a line, there are many answers that would work -12x-6y=0 -12x=6y x=-y/2 y=-2x
What is 8x plus y plus 4x plus 2y?
It simplifies to: 12x+3y
How can you get coefficients that are equal for x in 12x plus 6y equals 13 and 4x plus 6y equals 12?
Solving these simultaneous equations by the elimination method:- x = 1/8 and y = 23/12
What is the x value of 12x - 5y equals 30 y equals 2x - 6?
Substitute 2x - 6 for y in first equation: 12x - 5(2x - 6) = 30 ie 12x - 10x + 30 = 30 so 2x = 0 making x = 0 and y = -6
What is the x-coordinate of the of the vertex of y equals -3x2 plus 12x-5?
You can find the x-coordinate of it's vertex by taking it's derivative and solving for zero: y = -3x2 + 12x - 5 y' = -6x + 12 0 = -6x + 12 6x = 12 x = 2 Now that we have it's x coordinate, we can plug it back into the original equation to find it's y coordinate: y = -3x2 + 12x - 5 y = -3(2)2 + 12(2) + 5 y = -12 + 24 + 5 y = 17 So the vertex of the parabola y = -3x2 + 12x - 5 occurs at the point (2, 17).
If 2x plus 1 equals y what does 12x plus 6 equals?
6y
Y equals -x plus 12x-y equals 5 solve by substitution?
17
What is the line of symmetry for the graph of y equals -3x2 plus 12x - 11?
-2
What is the x intercept for y equals -3x2 plus 12x-9?
1 and 3
Find the x-coordinate of the vertex y equals x exponent 2 plus 12x plus 21?
y = x2 + 12x + 21At the max or min point, the first derivative of the function = 0.2x + 12 = 02x = -12x = -6
What is the vertex of the parabola y equals 2x squared plus 12x 13?
(-3, -5)
What is the equation of a line that is parallel to 3y equals -12x plus 9 and that has a y-intercept of -4?
y = - 4x - 4
What is the value of y for the equations x-y equals 120 and x plus y equals 150?
15
What is X plus y equals 120 x plus y equals 150?
It's an inconsistent pair of equations, for which there is no solution.
What is the solution of the following linear system 12x plus 6y equals 9 4x plus 2y equals 0?
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...
What is the answer to 60 plus 5y plus 60 equals 120?
The answer is y=0 .
What is the y value of x - y equals 120 x plus y equals 150?
15 (x = 135)
