What is the solution to this equation 17x - 8x - 9 76 - 40?
9x - 9 = 36 9x = 45 x = 5
What is 8x plus 9x?
8x + 9x = x(8 + 9) = x(17) = 17x
What is 9x plus 8?
Integral : 9x + 8 = 9(x squared)/2 + 8x Differential : 9x +8 = 9
How do you solve 2xsquared-9x equals 18?
2x2 - 9x = 18 2x2 - 9x -18 = 0 (2x - 18)(x + 9) x= -9 and 9
-8x plus 7 equals -7x-2?
-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
What is the answer to 8x plus 8 equals 9x-18 plus 9?
8x+9=9x-18+9 = 8x+9=9x-9 = 1x=0 (:
17x - 8x - 11 equals 100 - 30?
9x = 100 - 30 + 11 9x = 81, x = 9
What is x if 8x plus 3x plus 6 equals 24 plus 9x?
X equals 9.
What is the solution to this equation 17x - 8x - 9 76 - 40?
9x - 9 = 36 9x = 45 x = 5
What is 8x plus 9x?
8x + 9x = x(8 + 9) = x(17) = 17x
What is 9x plus 8?
Integral : 9x + 8 = 9(x squared)/2 + 8x Differential : 9x +8 = 9
8x plus x equals 1 -8x plus 3x equals -3?
8x + x = 1 -8x + 3x = -3 Clean up 9x = 1 -5x = -3 x = 1/9 x = 3/5 Two different answers. If you were expected to solve them simultaneously, this would be an incompatible set, returning an answer of {Φ} ■
Square root of 9x-9 plus 5 equals 10?
sqrt(9x-9) + 5 = 10Subtract 5 from each side:sqrt(9x-9) = 5Square each side:9x - 9 = 25Add 9 to each side:9x = 34Divide each side by 9:x = 34/9 or 3-7/9
What is the answer of 9x-5 equals 13?
9x-5 = 13 Add 5 to both sides: 9x = 18 Divide both sides by 9: x = 2
What is the answer to7x plus 9 equals 9x-1?
x = 5
-6-6x equals 9-9x what is x equal to?
it's an easy one :)-6 - 6x = 9 - 9x-6x + 9x = 9 + 63x = 15x = 15/3X = 5
What is the equation of that line that passes through the centre of the circle 2x2 plus 2y2 -8x -5y -1 equals 0 and is perpendicular to the line 4x plus 9y plus 5 equals 0?
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
