Answer:
<h2>C. (3, -4)</h2>
Step-by-step explanation:
If the system of linear equations is graphed, then the solution is the intersection of lines.
Read it from the graph (look at the picture).
 
        
             
        
        
        
The correct answer:
______________________________________________________
Explanation:
______________________________________________________
Assuming you mean:
" √(9a²)  +  (√49b)  −  a  +  √b " ;
Simplify the expression:
_________________________________________________________
Note that:  " √(9a²) = 3a " ;
                   "√(49b) = 7√b " ;   
And we write the expression
   →  " 3a  +  7√b  −  a  + √b " ; 
Combine the "like terms:
   " + 3a − a  =  2a " ;
   " +  7√b  +  1√b   =  8√b " ; 
Rewrite:  
________________________________________________________
    " 2a  +  8√b " ;  which is:  Answer choice:  [C]:  " 2a  +  8√b " .

Answer:
y=x+1
Step-by-step explanation:
As you can see, the slope is clearly 1 and the line starts at (0, 1), which is its y-intercept.
Plug the variables into this formula: y=mx+b, then you will get y=x+1.
