No, in 2x+7=27, x=10. In 3x+1=28 x =9, so it doesn't.

Find the general solution of the differential equation and check the result by differentiation. (Use C for the constant of integ
tensa zangetsu [6.8K]

Answer:

y=3t^9+C

Step-by-step explanation:

Given:  \dfrac{dy}{dt}=27t^8

We want to obtain the general solution of the given differential equation.

dy=27t^8$ dt\\$Take the integral of both sides\\\int dy =\int 27t^8$ dt$\\y=\dfrac{27t^{8+1}}{8+1} +C$, (where C is the constant of integration)$\\y=\dfrac{27t^{9}}{9} +C\\\\y=3t^9+C

The general solution of the differential equation is: y=3t^9+C

CHECK:

\dfrac{d}{dt} y=\dfrac{d}{dt}(3t^9+C)=\dfrac{d}{dt}(3t^9)+\dfrac{d}{dt}(C)\\\\\text{Since derivative of a constant is zero}\\\\\dfrac{dy}{dt}=27t^{9-1}\\\dfrac{dy}{dt}=27t^8

frutty [35]

Answer: Look down below

Step-by-step explanation: .Horizontal lines are functions that have a range that is a single value. Vertical lines are not functions. The equations y=±√x and x2+y2=9 are examples of non-functions because there is at least one x-value with two or more y-values.
