4x = 0 Divide both sides by 4: x = 0/4 = 0. This is the line x = 0, or the y-axis. All vertical lines have an undefined slope. 5y = 0 Divide both sides by 5: y = 0/5 = 0. This is the line y = 0, or the x-axis. All...

Well... m = (5 + 1)/(-3 + 6) = 4/3 Then... y - 5 = 4/3 * (x + 3) 3(y - 5) = 4(x + 3) 3y - 15 = 4x + 12 So... 4x - 3y = -27 [in standard form] y = 4x/3 + 9 [in slope-intercept form] Good luck!

use slope point form of equation of a st. line. (y-6) = (2/3)(x - (-3)) or 3y -2x = 24...(ans) general slope point eqn is (y - y1) = m(x - x1)

I'm not sure what language you are expected to use, whether you are expecting the user to input the values and then have them output, etc. But here's a general description of the algorithm along with the input that is expected and the output that...

I don`t seem to think that there is a symbol as such. Power factor is cos ø where cos ø = Resistance / Impedance

if they are parallel, the gradient will be the same, so differentiate each function: 1/x become -1/x^2 rearrange and differentiate 4x+9y=3: y=1/3-4x/9 dy/dx=-4/9 equate these: -1/x^2=-4/9 solve: x^2=9/4 x=3/2 or -3/2 put this x value into original equation: y=1/x y=2/3 or -2/3

Octants are stone age. Just say x<0? Before starting, you make the argument that the entire region is symmetric about xz plane and the integrand is an odd function of y, so you can just remove the +y part. The integral on the part of the region where y>0...

If x is odd, then either x = 4k + 1 or x = 4k + 3 for some integer k. If x = 4k + 1, then x^2 - 1 = (4k + 1)^2 - 1 = 16k^2 + 8k = 8(2k^2 + k) is clearly divisible by 8. If x = 4k + 3, then x^2 - 1 = (4k + 3)^2 - 1 = 16k^2 + 24k + 8 = 8(2k^2 + 3k + 1) is clearly divisible by 8...
