What is Y if Y2 plus 6y-9 equals 0?
Y = 1.125 2Y + 6Y - 9 = 0 2Y + 6Y = 9 Y(2+6) = 9 8Y = 9 Y = 9/8 = 1 1/8 = 1.125 PROOF: 2(1.125) + 6(1.125) - 9 = 0 2.5 + 7.5 - 9 = 0 9 - 9 = 0
3x -6y equals 9 5x plus 4y equals -27?
3x - 6y = 9, 5x + 4y = -27 6x - 12y = 18, 15x + 12y = -81 21x = -63 x = -3 (3 x -3) = 9 + 6y (-9 - 9)/6 = y y = -3 Check: (5 x -3) + (4 x -3) = -15 -12 = -27 QED

6y equals 8-9 plus 6y Find the value of y?
Two ways to see this: 6y=8-9+6y 6y=6y-1 No answer here 6y= 8-(9+6y) 6y+(9+6y)=8 12y+9=8 12y=-1 y= -(1/12) or -0.08333...
What is the answer to 7y-8 equals 6y plus 1?
7y-8 = 6y+1 7y-6y = 1+8 y = 9
What is the slope of -9x plus 6y equals 54?
-9x+6y = 54 6y = 9x+54 y = 1.5x+9 slope = 1.5
-6y plus 14 plus 4y equals 32?
-6y + 14 + 4y = 32-2y = 32 - 14-2y = 18y = - 9
How do you factor 8y3 plus 27?
(2y + 3)(4y^2 - 6y + 9)
What does 4x plus 6y equals 24 7x plus 6y equals 9?
It does nothing! 4x + 6y = 24 7x + 6y = 9 Subtracting the first equation from the second gives: 3x = - 15 so that x = -5 Substituting the value of x in the first equation gives -20 + 6y = 24 so that 6y = 44 and so y = 22/3 or 71/3
What is y if -6y - 9 equals 5y plus 24?
-6y - 9 = 5y + 24Add 6y to each side of the equation:-9 = 11y + 24Subtract 24 from each side:-33 = 11yDivide each side by 11:-3 = y
Factor 8y3 plus 27?
(2y + 3)(4y2 - 6y +9)
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 are the variables of 7x plus 6y-9?
The variables in the given expression are x and y
What is Y if Y2 plus 6y-9 equals 0?
Y = 1.125 2Y + 6Y - 9 = 0 2Y + 6Y = 9 Y(2+6) = 9 8Y = 9 Y = 9/8 = 1 1/8 = 1.125 PROOF: 2(1.125) + 6(1.125) - 9 = 0 2.5 + 7.5 - 9 = 0 9 - 9 = 0
