Answer:
26
Step-by-step explanation:
Fitst,  you substitute
f(2) = 3(2) + 20
f(2) = 6 + 20
f(2) = 26
your answer is 26
 
        
                    
             
        
        
        
Answer:
A:38 c:54 
Step-by-step explanation:
First off, I did the easiest which was a. i found the value of A by subtracting 180 by 142. because a flat line is 180 degrees. 
For C, It was more difficult. I subtracted 88 by the value of A, since the value of A is the same as the one next to 88. So I subtracted 126 (88+38) and got 54.  
Fortunately, I couldn't figure out B though, but i think it is a similar answer to c.   
 
        
             
        
        
        
Answer:

Slope = (-8 - 4)/(-4 -0) = -12/-4 = 3
y-intercept so b = 4
equation: y = 3x + 4
answer: <span>C. y = 3x + 4</span>
