In which quadrant does 2 - 7i lie? I II III IV
1 answer:
This is a problem of complex number. So we have a coordinate system with two axis. The horizontal axis represents the real numbers and the vertical axis represents the imaginary numbers. Given that a complex number is given by the form a + bi, if we set the point 2 - 7i on the coordinate system it is obvious that lies over the IV quadrant.

Answer:
The ordered pair solutions are:
C. (1,-3)
E. (2,5)
Step-by-step explanation:
Given inequality:
To check from the list of ordered pairs which are the solution of the inequality.
Solution:
In order to check for the solutions to the inequality, we will plugin the ordered pairs in the inequality and check if it holds true. Each ordered pair is in the form .
Plugging in each ordered pair in the given inequality to find the solutions.
<em>A) (-3,-2)</em>
The above statement can never be true and hence it is not a solution.
<em>B) (3,14)</em>
The above statement can never be true and hence it is not a solution.
<em>C) (1,-3)</em>
<u>The above statement is always true and hence it is a solution.</u>
<em>D) (1,6)</em>
The above statement can never be true and hence it is not a solution.
<em>C) (2,5)</em>
<u>The above statement is always true and hence it is a solution.</u>
