Answer:
I am not positive that this is correct
Step-by-step explanation:
So if she want to reach a reef that has a elevation of -60 and she descends at a rate of 10 feet my guess the rational number that would represent this problem would be
-60/10
 
        
             
        
        
        
The pattern of a linear function, is the following:
y  = mx + b
Where m is always the slope.
m in this case is -4, hence
The correct answer for your question is -4.
        
                    
             
        
        
        
5(x+3)=7x-3 which is the equation, then we solve for it, and the answer is 9
        
             
        
        
        
1) Tanθ= opposite/adjacent 
 θ=Tan-1(9/7)
 θ=52.125 = 52 degrees 
2) Cosθ= adjacent/hypothesis 
 θ=Cos-1(5/12)
 θ=65.376 = 65 degrees
