What are solutions for x2 plus 10x plus 1 equals -12 plus 2x?
x2+10x+1 = -12+2x x2+8x+13 = 0 The solution: x = -4 + the square root of 3 or x = -4 - the square root of 3
What is the solution to x2 plus 10x plus 1 equals -12 plus 2x?
x2+10x+1 = -12+2x x2+10x-2x+1+12 = 0 x2+8x+13 = 0 Solving by using the quadratic equation formula: x = - 4 - or + the square root of 3
What is 3 plus 3x plus 7x equals 13?
3+3x+7x=13 3x+7x=10 10x=10 x=1
4x plus 13 equals 93-6x what does x equals?
4x +13 = 93-6x. Adding 6x to each side gives: 10x+13 = 93. Subtracting 13 from each side gives: 10x = 80. Dividing both sides by 10 gives: x = 8.
What is 3x-7 equals 5x plus 13?
3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
What is the solution for 10x plus 13 equals 17?
10x + 13 = 17 ie 10x = 17 - 13 so x = 4/10 = 0.4
What are solutions for x2 plus 10x plus 1 equals -12 plus 2x?
x2+10x+1 = -12+2x x2+8x+13 = 0 The solution: x = -4 + the square root of 3 or x = -4 - the square root of 3
What is the solution to x2 plus 10x plus 1 equals -12 plus 2x?
x2+10x+1 = -12+2x x2+10x-2x+1+12 = 0 x2+8x+13 = 0 Solving by using the quadratic equation formula: x = - 4 - or + the square root of 3
What is the substitution method for y equals 5x plus 8 and y equals 10x plus 3?
5x+8 = 10x+35x-10x = 3-8-5x = -5x = 1 and by substituting the value of x into the equations y = 13
What is 3 plus 3x plus 7x equals 13?
3+3x+7x=13 3x+7x=10 10x=10 x=1
Find the value of x if 13 plus 2x equals 3?
13 + 2x = 32x = 3 - 132x = -10x = -5
4x plus 13 equals 93-6x what does x equals?
4x +13 = 93-6x. Adding 6x to each side gives: 10x+13 = 93. Subtracting 13 from each side gives: 10x = 80. Dividing both sides by 10 gives: x = 8.
What is 3x-7 equals 5x plus 13?
3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
How do i complete the square x squared plus 10x minus 13 equals 17 how do you complete the square x squared plus 10x minus 13 equals 17?
X2 + 10X - 13 = 17 add 13 to each side X2 + 10X = 30 halve the linear coefficient ( 10 ), square it and add it to both sides X2 + 10X + 25 = 30 + 25 factor on the left and gather terms on the right (X + 5)2 = 55 (X + 5)2 - 55 = 0 ---------------------------vertex form, (- 5, - 55 ), is the vertex -------------------------------------------[-------------------------------]
What is the solution of 3x plus 2y equals 13 and 2x plus 3y equals 12?
x = 3 and y = 2
1- Which of the ordered pairs is a solution of 2x plus 3y equals 13?
2x plus 3y
What is the mistake in this solving of an equation 3x minus 12 equals 10x minus 15 minus 6x minus 10 3x minus 12 equals 4x minus 25 3x plus 13 equals 4x 13 equals x?
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
