How many values of x and y satisfy the equations 2x plus 6y equals 12 and 3x plus 9y equals 18?

2X + 6Y = 12 3X + 9Y = 18 try elimination - 3(2X + 6Y = 12) 2(3X + 9Y = 18) - 6X - 18Y = - 36 6X + 18Y = 36 ================= I will say this system is dependent and an infinite number of solutions can be found.


Find the x- and y-intercept of the line with equation -3x + 9y = 18?

Answer: The x-intercept of the line is -6 and the y-intercept of the line is 2. Solution: The x-intercept of a line is the x-coordinate of a point where the line intersects the x-axis. Solve for this by substituting y = 0. -3x + 9y = 18 -3x + 9(0) = 18 -3x = 18 x = 18/-3 x = -6 The y-intercept of a line is the y-coordinate of a point where the line intersects the y-axis. Solve for this by substituting x = 0. -3x + 9y = 18 -3(0) + 9y = 18 9y = 18 y = 18/9 y = 2


What is the slope-intercept form of -3x plus 9y equals 6?

-3x+9y = 6 9y = 3x+6 y = 1/3x+2/3


What are the intercepts of the graph of the equation 3x-9y-27?

3x-9y-27


How do you factor 3x squared plus 25xy-18 squared?

If that's -18y2, the answer is (3x - 2y)(x + 9y)


Y-8x plus 9y equals?

Y-8x plus 9y equals 10y-8x.


10y equals 2y plus 4 plus 7y?

10y = 9y + 4, so y = 4


Answer the algebra questions?

-3x+9y=18; find the x and y intercept of the line


What is -3x 9y-6 in slope intercept form?

If you mean: -3x+9y = -6 then it is y = 1/3x-2/3


How can you graph 3x-9y equals 27?

3x - 9y = 27-9y = -3x + 279y = 3x - 27y = x/3 - 3The graph is a straight line, with (slope = 3), and passing through the point (y = - 3) on the y-axis.


How do you solve -3x plus 9y equals 18?

First, you want to get the y on one side of the equation and everything else on the other side. To do this, add 3x to each side: 9y = 3x + 18 The next step is to divide both sides by 9, which gives you the equation solved for y: y = x/3 + 2


Solve the equation10y equals 6y plus 5 plus 3y?

10y= 6y+5+3y 10y=6+9y y=6
