How do you graph y equals x squared -4x plus 2?
y=xsquared-4x+2
What is 4x plus 3y equals 12 in slope intercept form?
4x+3y = 12 3y = -4x+12 y = -4/3x+4
How do you work out what x and y are equal to using x squared plus y squared equals 25 and y equals 3x plus 1?
since y = 3x+1 we have y squared =(3x+1) squared x^2 + y^2 = 25 x^2 + (3x+1)^2=25 x^2 + 9x^2+ 6x+1 = 25 10x^2 + 6x + 1 = 25 10x^2 + 6x -24 = 0 solve x from quadratic formula x = 1.28 y = 3x + 1 = 4.83
What is the answer to y equals 3x plus 3 and y equals 4x plus 5?
y=3x+3 -- This could be the formula for a line, where the slope is 3 and the y intercept is (0,3). In the next line the slope would be 4 and the y-intercept would be 5
What is the slope of the line 3x plus 4y 12?
If you mean: 3x+4y = 12 then y = -3/4x+3 whereas -3/4 or -0.75 is the slope and 3 is the y intercept
How do you factor 9x squared plus 12x plus 4 - y squared?
(3x - y+ 2)(3x + y + 2)
What is 2x-3x plus 4x plus 3y-2y?
3x + y
What is the length of the line that spans the parabolas of y equals 4x squared -2x -1 and y equals -2x squared plus 3x plus 5?
If: y = 4x2-2x-1 and y = -2x2+3x+5 Then the length of the line works out as: 65/18 or 3.6111 ... recurring decimal 1
Factor 3x squared plus 6xy plus 3y squared?
(3x + 3y)(x + y) = 3(x + y)2
Simplified form of -6 plus 3x minus y minus 4x plus 4y plus 5?
-6 + 3x - y - 4x + 4y + 5 (combine like terms) = (-6 + 5) + (3x - 4x) + (-y + 4y) = -1 - x + 3yHope this helps :)
4x plus 2y-3x plus 4-y?
It is equivalent to x + y + 4.
How do you graph y equals x squared -4x plus 2?
y=xsquared-4x+2
What is equivalent to 3x plus 5 plus x plus 10 plus 2y?
3x + 5 + x + 10 + 2y 4x + 2y + 15 |:2 2x + y + 7.5 2x + y + 7.5 is equivalent to the original.
What are the points of contact when the parabolas of y equals 4x squared -2x -1 and y equals -2x squared plus 3x plus 5 intersect with each other?
If: y = 4x^2 -2x -1 and y = -2x^2 +3x+5 Then: 4x^2 -2x-1 = -2x^2 +3x+5 or 6x^2 -5x -6 = 0 Factorizing the above: (3x+2)(2x-3) = 0 meaning x = -2/3 or x = 3/2 By substitution points of contact are at: (-2/3, 19/9) and (3/2, 5)
What are the points of contact of the following parabolas y equals 4x squared -2x -1 and y equals -2x squared plus 3x plus 5?
If: y = 4x^2 -2x -1 and y = -2x^2 +3x +5 Then: 4x^2 -2x -1 = -2x^2 +3x +5 Transposing terms: 6x^2 -5x -6 = 0 Factorizing: (3x+2)(2x-3) = 0 => x = -2/3 or x = 3/2 By substitution the points of contact are at: (-2/3, 19/9) and (3/2, 5)
Solve by substitution 3x plus 2y equals 6 4x-y equals 2?
4x-y=2, thereforey=4x-2sub y into 3x+2y=6...3x+8x-4=611x=10x=10/11
Factor 9x squared minus 6xy plus y squared minus 81?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
