Answer:
The Answer is: y = 2x - 3
Step-by-step explanation:
Given points: (3, 3) and (4, 5)
Find the slope, m:
m = y - y1/(x - x1)
m = 3 - 5/(3 - 4)
m = -2/-1 = 2
Use the Point Slope form of the equation:
y - y1 = m(x - x1)
y - 5 = 2(x - 4)
y - 5 = 2x - 8
y = 2x - 8 + 5
y = 2x - 3
Proof:
f(3) = 2(3) - 3 
= 6 - 3 = 3, giving (3, 3)
 
        
                    
             
        
        
        
F(-5)=3(-5)+4=-11
g(-2)=4(-2)^2+2=18
        
             
        
        
        
Answer:
14. congruent means "THE SAME" so it will be "A" because there all the same letter. 
15. D
 
        
             
        
        
        
The answer is x=20. You isolate the square root. Eliminate the radical on the left handside. And then solve it!
        
                    
             
        
        
        
So 1 would be 5r+20 and then the second one would be
