Solution for y=7/((-8x-9)^1/2) equation:


D( x )

((-8*x-9)^1)/2 = 0

((-8*x-9)^1)/2 = 0

((-8*x-9)^1)/2 = 0

(-8*x-9)/2 = 0

-8*x-9 = 0 // + 9

-8*x = 9 // : -8

x = 9/(-8)

x = -9/8

x in (-oo:-9/8) U (-9/8:+oo)

y = 7/(((-8*x-9)^1)/2) // - 7/(((-8*x-9)^1)/2)

y-(7/(((-8*x-9)^1)/2)) = 0

y-14*(-8*x-9)^-1 = 0

y-14/(-8*x-9) = 0

(y*(-8*x-9))/(-8*x-9)-14/(-8*x-9) = 0

y*(-8*x-9)-14 = 0

-8*x*y-9*y-14 = 0

(-8*x*y-9*y-14)/(-8*x-9) = 0

(-8*x*y-9*y-14)/(-8*x-9) = 0 // * -8*x-9

-8*x*y-9*y-14 = 0

-8*x*y-9*y-14 = 0 // + -9*y-14

-8*x*y = -(-9*y-14) // : -8*y

x = (-(-9*y-14))/(-8*y)

x = (14-(-9*y))/(-8*y)

x = (14-(-9*y))/(-8*y)
