If you mean x+2y = -2 and 3x+4y = 6 then the solutions to the equations are x = 10 and y = -6
It is a cubic function of y.
Centre of circle: (2, 1.25) Slope of line: 9/4 Equation of line: y-1.25 = 9/4(x-2) => 4y-5 = 9x-18 => 4y = 9x-13
88 + 5y - y2 66 - 3y + y2 Subtract: 22 + 8y -2y2
2ay2 + 5ay - 3a = a(2y2 + 5y - 3) = a(2y - 1)(y + 3)
6x^3y^2
6y3 + 8y2 - 15y - 20 is an expression, not an equation (or inequality). An expression cannot be solved.The expression factorises to (3y + 4)*(2y2 - 5)
-5
2(y - 3)(y - 10)
It is a cubic function of y.
2y2 + y = -11yAdd 11y to each side of the equation:2y2 + 12y = 0Divide each side by 2:y2 + 6y = 0Factor the left side:y (y + 6) = 0The equation is true if either factor is zero:y = 0or (y + 6) = 0y = -6
this equals to 12
Yes, 18y3 + 2y2 + 1 is a polynomial; it is a cubic expression. If it were expanded to form an equation, then it would be a cubic equation (or higher), capable of solution.
y2 + y2 = 2y2
10x2y2 + 8xy2 - 210y2 = 2y2(5x2 + 4x - 105) = 2y2(5x2 + 25x - 21x - 105) = 2y2(x + 5)(5x - 21).
The y-intercept is the place (or places) where x=0 . So if 'x' is 2y2+3y+1 , then all you have to do is find places where 2y2+3y+1 is zero, and those are your y-intercepts.
All six of them
Question: x = 2y2 +3 if x = 53 what NEGATIVE value of y makes this an equality Answer: x= 2y2 + 3 53 = 2y2 + 3 53 - 3 = 2y2 50/2 = y2 25 = y2 Take the Square Root of Both sides so we can get: y = Square root of 25 so: y = EITHER 5 or -5 Then the ANSWER is -5 (since we need the NEGATIVE Value of Y)
