If x equals 10 and y equals 10, then 9x plus 8y equals 170.
9x+27 = -81 9x = -81-27 9x = -108 x = -12
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0
-9x+6y = 54 6y = 9x+54 y = 1.5x+9 slope = 1.5
9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
9x+18 = 180 9x = 180-18 9x = 162 x = 18
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
8x+9=9x-18+9 = 8x+9=9x-9 = 1x=0 (:
x^2-9x+18=(x-6)(x-3)
x2 - 9x + 18 = (x - 3)(x - 6)
x2+9x+18 find factors of 18 that add up to 9, in this case 6&3 (x+6)(x+3)
180=11x+9x. 180 = 20x. 18=2x. 9=x.
9x + 3y = -54 3y = -9x - 54 y = -(3x + 18) Therefore, the y-intercept of this equation is y=-18.
use algebra and then factor... x= -9 and 9
102 +9x +4 = 9x + 106, which is in its simplest form.
it equals 13X.
The slope is 0.
