Hitman42 [59]

$\frac{dw}{dt} = \frac{dx}{dt} \times \frac{dw}{dx} + \frac{dy}{dt} \times \frac{dw}{dy} + \frac{dz}{dt} \times \frac{dw}{dz} \\ \frac{dw}{dt} = 3t ^{2} \times {e}^{ \frac{y}{z} } + - t \times \frac{x {e}^{ \frac{y}{z} } }{z} + 4 \times - \frac{xy {e}^{ \frac{y}{z} } }{ {z}^{2} } \\ \frac{dw}{dt} = \frac{ {e}^{ \frac{y}{z} } (3 {t}^{2} {z}^{2} - tzx - 4xy)}{ {z}^{2} }$

Solve y = x2 +11 for x.

Hunter-Best [27]

Answer:

x = ±sqrt(y-11)

Step-by-step explanation:

y = x^2 +11

Subtract 11 from each side

y -11 = x^2 +11-11

y-11 = x^2

Take the square root of each side

±sqrt(y-11) = sqrt(x^2)

±sqrt(y-11) = x
