<h2>Answer:</h2>

The domain of y=cot x is:

Option: b

b. (0,π)

<h2>Step-by-step explanation:</h2>

We know that a domain of a function is the set of all the possible x values for which the function is well defined.

We are given a function as:

$y=\cot x$

which is further defined as:

$y=\dfrac{\cos x}{\sin x}$

Hence, the function is well defined when the denominator term is non-zero.

We know that the denominator term i.e. the sine function is zero at the points:

$x=0,\pi,2\pi,3\pi,.....$

Hence, the best possible option is:

b. (0,π)

Written out numerically, it is 4x4x4. To work this out you multiply 4x4= 16 and then you have one more 4 to multiply by, so you multiply 16x4=64

-4x - 6y = 6<br> 4x + 6y = -4

Sloan [31]

Step-by-step explanation:

$-4x - 6y = 6$

$4x + 6y = -4$

To solve a system of equations, we can add the two equations and solve for one of the remaining variables -- let's try to eliminate the $x$ variable when we add the two equations together.

Right now, there's a $-4x$ term in the first equation, and a $4x$ term in the second equation, so if we add those together, we'll be able to eliminate the $x$ variable altogether and solve for $y$ .

However, when we also have a $-6y$ term in the first equation and $6y$ term in the second equation, so adding these together will also eliminate the $y$ term, leaving a $0$ on the left-hand side of the equation.

If we add the two numbers on the right side of the equation, we get $-2$ , which does not equal $0$ , meaning there are no solutions to this system of equations.
