Not sure what form you want this in: 
Simplified this is 4x+4y
Factorised this is 4(x+y) 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
(0, -3) not a solution
(2,1) solution
(3,-4) not a solution
(-5,7) solution
 
        
             
        
        
        
1 1/2 divided by 1 1/6 equals 1.28571429
Rounded: 1.28, 1.29, or 1.30 (depends on what they ask for)
3/4 divided by 1 3/8 equals 0.54545455
Rounded: 0.54 or 0.55
        
             
        
        
        
Answer:
 The range stays the same. 
 The domain stays the same.   
Step-by-step explanation:
 The function  is an exponential function, where <em>a</em> is the coefficient, <em>b</em> is the base and <em>x</em> is the exponent.
 is an exponential function, where <em>a</em> is the coefficient, <em>b</em> is the base and <em>x</em> is the exponent.
 The domain for this kind of functions is: All real numbers.
 And the range is: (0,∞); this happen because the exponential functions are always positive when <em>a</em>>0. 
 Therefore, if the value of <em>a</em> is increased by 2, the domains will stay the same and the range will stay the same: (0,∞). The coefficient does not change the domain or the range if it keeps the same sign.
 
        
                    
             
        
        
        
$11.7 is the total price.
To solve. do 10 + (.17*10).
