Answer:
The answer to your question is because it is a solution of each equation.
Step-by-step explanation:
Data
Point (3,4)
Equation l     y = 1/3x + 3
Equation ll     y = 2x - 2
Process
1.- To test is a point is solution to a system of equations, 
-Substitute the point in both equations 
Equation l            4 = 1/3(3) + 3
                             4 = 1 + 3
                             4 = 4               The point is a solution because 
                                                      4 = 4
Equation ll            4 = 2(3) - 2
                              4 = 6 - 2
                              4 = 4               This point is a solution for the second
                                                      equation but not for the first one.
2.- Conclusion
As the point is a solution of each equation, it is a solution of the system.
 
        
             
        
        
        
Answer:
A=lw+l(w
2)2+h2+w(l
2)2+h2
Step-by-step explanation:
 
        
                    
             
        
        
        
3 ( 2t + 5 ) = 5 t + 25
3 * 2 t + 3 * 5 = 5 t + 25
6 t + 15 = 5 t + 25
6t - 5t = 25 - 15
t = 10
Hope this helps!
        
                    
             
        
        
        
<span>STEP 1: Stick a "y" in for the "f(x)" guy:STEP 2: Switch the x and y. ( because every (x, y) has a (y, x) partner! ):STEP 3: Solve for y:<span>STEP 4: Stick in the inverse notation, continue. 1 2 3.
these are the steps and that is not correct </span></span>
