2x+y=6
3x+5y=9
y = 6 - 2x
3x + 5( 6-2x ) = 9
3x + 30 - 10z = 9
7x = 21
x = 3
y = 6 - 2(3)
y = 0
Answer: D is the right answer

Answer:
The value of cot theta is undefined for all the options
Step-by-step explanation:
I think the best way to go about this is by the use of a calculator.
All that needs to be done is to input the individual values to see where we have an answer that is out of it.
Now, moving away from the calculators, we know quite well that cot is a derivative of tan.
By knowing the values at which we have tan as undefined, we can appropriately see values where cot too would be undefined.
On a normal scientific calculator, there is no cot functionality.
The way around this is to express
Cot theta as 1/tan theta
Thus cot 90 = 1/cot(90) = calculation error
Cot 180 = 1/tan (180) = calculation error
Cot 270 = 1/tan 270 = calculation error
Cot 450 = 1/tan (450) = calculation error
This shows that the value of cot is undefined for all of these options
Line segments are taken to line segments of the same length;
angles are taken to angles of the same measure; and.
lines are taken to lines and parallel lines are taken to parallel lines.
Hope this helps!
