Find conditions on k that will make the following system of equations have a unique solution. To enter your answer, first select whether k should be equal or not equal to specific values, then enter a value or a list of values separated by commas. Then give a formula in terms of k for the solution to the system, when it exists. Be sure to include parentheses where necessary, e. g. to distinguish 1/(2k) from 1/2k.3kx+3y = 43x+3ky = 1The system has a unique solution when k (equal or not equal) to ???The unique solution is x = y =

Step-by-step explanation:

First we see that 3k/3 can't be equal to 3/3k, so we have

, i.e, k can't be -1 or 1.

multiple first equation with k:

then we have:

i.e,

And now we calc y:

for any k not eql to -1 or 1.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
