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>

we know that
1) First way to find the value of a
in the triangle ABC
<span>applying the Pythagorean theorem
AC</span>²=AB²+BC²--------> BC²=AC²-AB²-----> BC²=25²-15²-----> BC²=625-225
BC²=400--------> BC=20 units
a=BC
a=20 units
2) Second way to find the value of a
in the triangle ABD
AB²=AD²+BD²--------> BD²=AB²-AD²-----> BD²=15²-9²---> BD²=144
BD=12 units
in the triangle BDC
a=BC
BC²=BD²+DC²-----> 12²+16²----> 144+256------> BC²=400
BC=20 units
a=20 units
