Answer:
(12,-6)
Step-by-step explanation:
we have
 ----> inequality A
 ---> inequality B
we know that
If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities (makes true both inequalities)
<u><em>Verify each point</em></u>
Substitute the value of x and the value of y  of each ordered pair in the inequality A and in the inequality B 
case 1) (0,-1)
Inequality A

 ----> is true
Inequality B

 ----> is not true
therefore
The ordered pair is not a solution of the system
case 2) (0,3)
Inequality A

 ----> is true
Inequality B

 ----> is not true
therefore
The ordered pair is not a solution of the system
case 3) (-6,-6)
Inequality A

 ----> is true
Inequality B

----> is not true
therefore
The ordered pair is not a solution of the system
case 4) (12,-6)
Inequality A

 ----> is true
Inequality B

 ----> is true
therefore
The ordered pair is a solution of the system (makes true both inequalities)
 
        
             
        
        
        
Answer:
6
Step-by-step explanation:
P(6) = ⅙
Expected no. of trials for first 6:

Answer:
122
Step-by-step explanation:
The exterior angle of a triangle is the sum of the opposite interior agnles
32+90 =x
122 =x
