4x2 - 4x plus 2xy - 2y?
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) = (x - 1)(4x + 2y) = 2(x - 1)(2x + y)
How do you simplify -5(x plus 2y)-3x plus 8y plus 5?
-5(x + 2y) -3x + 8y + 5 = -5x -10y -3x + 8y + 5 = -8x -2y + 5
What is the answer to the following system x plus 2y equals -5 and 2x plus 3x equals -9?
x + 2y = -5 2x + 3x = -9 5x = -9 x + 2y = -5 x = -2y - 5 5(-2y - 5) = -9 -10y - 25 = -9 -10y = 16 y = -5/8 x = -2y - 5 x = -2(-5/8) - 5 x = -5/4 - 5 x = -25/4 (-25/4, -5/8)
What are the solutions to the simultaneous equation 3x plus 2y equals 5 and x plus 2y equals 7?
3x + 2y = 5x + 2y = 7Subtract (2) from (1) to give: 3x - x + 2y - 2y = 5 - 7→ 2x = -2→ x = -1Substitute for x in (1)3(-1) + 2y = 5→ -3 + 2y = 5→ 2y = 8→ y = 4Substitute for x and y in (2) to check answer:x + 2y = -1 +2(4) = -1 + 8 = 7 as required. Thus:x = -1y = 4
2y plus 5x 13 2y and ndash 3x 5?
If you mean: 2y+5x = 13 and 2y-3x = 5 then x = 1 and y = 4
How do you factor 4x2-4x plus 2xy-2y?
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) (4x + 2y)(x - 1).
4x2 - 4x plus 2xy - 2y?
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) = (x - 1)(4x + 2y) = 2(x - 1)(2x + y)
How do you simplify -5(x plus 2y)-3x plus 8y plus 5?
-5(x + 2y) -3x + 8y + 5 = -5x -10y -3x + 8y + 5 = -8x -2y + 5
Is point 1 4 on the line represented by the equation x plus 2y equals 5?
The equation "x plus 2y equals 5" is: x + 2y = 5 2y = 5 - x y = 5/2 - 1/2x y = -1/2x + 5/2
What are the factors of 4x2 plus 21x plus 5?
(4x + 1)(x + 5)
What is the answer to the following system x plus 2y equals -5 and 2x plus 3x equals -9?
x + 2y = -5 2x + 3x = -9 5x = -9 x + 2y = -5 x = -2y - 5 5(-2y - 5) = -9 -10y - 25 = -9 -10y = 16 y = -5/8 x = -2y - 5 x = -2(-5/8) - 5 x = -5/4 - 5 x = -25/4 (-25/4, -5/8)
What is the factor of 4x2 plus 17x plus 15?
(x + 3)(4x + 5)
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.
How do you Substitute x equals y plus 3 into x plus 2y equals 9?
x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5
What are the solutions to the simultaneous equation 3x plus 2y equals 5 and x plus 2y equals 7?
3x + 2y = 5x + 2y = 7Subtract (2) from (1) to give: 3x - x + 2y - 2y = 5 - 7→ 2x = -2→ x = -1Substitute for x in (1)3(-1) + 2y = 5→ -3 + 2y = 5→ 2y = 8→ y = 4Substitute for x and y in (2) to check answer:x + 2y = -1 +2(4) = -1 + 8 = 7 as required. Thus:x = -1y = 4
2y plus 5x 13 2y and ndash 3x 5?
If you mean: 2y+5x = 13 and 2y-3x = 5 then x = 1 and y = 4
