Answer:
area of triangle : 1/2 x length x widht
 
        
             
        
        
        
The number at the end of the equation shifts the graph up or down.
Changing the 1/2 to a -2 would shift the graph down which would change the y-intercept.
The answer is D.
 
        
                    
             
        
        
        
Answer:
f(x) = 3 + 2
 + 2
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one because I answered this question once in Brainly as well. Please have a look at the attached photo. 
My answer: 
- Given G(x) =    
As we can see, the graph of f(x) is 2 units above the graphof g(x) in vertical (vertical shift)
=> f(x) = a + 2
 + 2
As you can see, the graph of f(x) is stretched vertically by a dilation factor of 3  and there is no reflection, so a= 3
=> the  equation of f(x) is:  f(x) = 3 + 2
 + 2  
Hope it will find you well. 
 
        
             
        
        
        
Answer:
6 and 7 
Step-by-step explanation:
we know that 42 will lie between 36 and 49 
 And 36=6; 49=7 
 so we can be sure that 42 lies between 6 and 7
 
        
             
        
        
        
Answer:
33.7º
Step-by-step explanation:
tan  = opp/adj
tan∅ = 100/150 = 2/3
∅ = arctan 2/3
∅ = 33.690067525979787
