What is the result of subtracting the second equation from the first?​
butalik [34]

Answer:

-5x + 7

Step-by-step explanation:

-4x - 2y = -2

x - 2y = 9

First, you're going to subtract the equations from each other.

(-4x - 2y = -2) - (x - 2y = 9)

Next, you need to get rid of the equal sign in both equations.

(-4x - 2y = -2) - (x - 2y = 9)

     +2       +2        -9      -9  

After you get rid of the equal signs, you will distribute the sign to the equation and then subtract everything.

-4x - 2y + 2 - x + 2y + 9

Now, combine the like terms.

(-4x -x) + (-2y + 2y) + (2 + 9)

Finally, calculate the terms and solve.

-5x + 7

Determine whether or not the vector field is conservative. if it is conservative, find a function f such that f = ∇f. (if the ve
Akimi4 [234]
A three-dimensional vector field is conservative if it is also irrotational, i.e. its curl is \mathbf 0. We have

\nabla\times\mathbf f(x,y,z)=-2e^{-x}\,\mathbf k

so this vector field is not conservative.

- - -

Another way of determining the same result: We want to find a scalar function f(x,y,z) such that its gradient is equal to the given vector field, \mathbf f(x,y,z):

\nabla f(x,y,z)=\mathbf f(x,y,z)

For this to happen, we need to satisfy

\begin{cases}f_x=ye^{-x}\\f_y=e^{-x}\\f_z=2z\end{cases}

From the first equation, integrating with respect to x yields

f_x=ye^{-x}\implies f(x,y,z)=-ye^{-x}+g(y,z)

Note that g *must* be a function of y,z only.

Now differentiate with respect to y and we have

f_y=-e^{-x}+g_y=e^{-x}\implies g_y=2e^{-x}\implies g(y,z)=2ye^{-x}+\cdots

but this contradicts the assumption that g(y,z) is independent of x. So, the scalar potential function does not exist, and therefore the vector field is not conservative.

1. What is the vertex of y-3=-(x+2)^2
KonstantinChe [14]
For #2, you need a value of x that will make y = 0. This is because the x-intercept is the value of x where the line crosses the x-axis.
