Which statement is true about the equations –3x + 4y = 12 and x – y = 1? The system of the equations has exactly one solution at

(–8, 3). The system of the equations has exactly one solution at (–4, 3). The system of the equations has no solution; the two lines are parallel. The system of the equations has an infinite number of solutions represented by either equation.

The equations to consider are:
-3x + 4y = 12
x - y = 1

To find the solution, we will use substitution. From the second equation,
x = 1 + y

Now, we will substitute this value of x into the first equation:

-3(1 + y) + 4y = 12
-3 - 3y + 4y = 12
y - 3 = 12
Solving for y gives us:
y = 15
Now substituting this value back to find x:
x = 1 + y = 1 + 15 = 16

Thus, the solution is (16, 15).

This indicates that the equations possess a unique solution: (16, 15).

Are the following statements true or false? 1. If F⃗ is a vector field in 3-dimensional space, and W is a solid region with boun
lawyer [12517]

Answer:

Step-by-step explanation:

1) True. This stems from the fact that the divergence of F is 1, indicating that F is a linear function. The orientation is outward from the surface. Integrating a linear function over a surface with outward orientation leads to the volume enclosed by that surface.

2) True. This is fundamentally what the Divergence theorem states.

3) False. Had F been specified as 3/pi instead of div(F), this claim would have held true.

4) False. The gradient of divergence can vary. The curl of the divergence of a vector function is 0, contradicting the notion of the gradient of divergence being 0.

5) False. While calculating divergence, derivatives are computed for different variables. Since the derivative of constants is 0, both vector functions F and G can contain distinct constant components even when their divergences are equal.
