Answer:
B: 39 degrees
Step-by-step explanation: The angles in a triangle add up to 180 degrees. 180 - 30 - 24 = 126. 
126 = (3x-9). 
126 - 9 = 117. 
117 / 3 = 39

Answer:
The domain is   and its range is
 and its range is 
The y-intercept is (0,3).
Step-by-step explanation:
Consider the parent function  Its domain is
 Its domain is  and its range is
 and its range is 
The graph of the function  is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the  domain and will change the range of the function, thus the domain is
 is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the  domain and will change the range of the function, thus the domain is   and its range is
 and its range is 
To find th y-intercept you have to find y at x=0:

Hence, the y-intercept is (0,3).
 
        
                    
             
        
        
        
147÷100=1.47
