Answer:
No solution
Option 4 is correct
Step-by-step explanation:
Given: The system of inequality 


We need to choose correct option. 
Option 1: (-5,2) 
Put x=-5 and y=2 
 Equation 1                               Equation 2 
 
                            
 
                                    
     TRUE                                     FALSE
Option 2: (2,2) 
Put x=2 and y=2 
 Equation 1                              Equation 2
 
                    
 
                                           
   FALSE                                      FALSE
Option 3: (5,2) 
Put x=-5 and y=2 
 Equation 1                            Equation 2
 
                      
 
                                           
  FALSE                                      TRUE
Option 1, 2 and 3 are incorrect because both equation must be true for solution. 
Hence, Option 4 is correct no solution.  
 
        
                    
             
        
        
        
Hey there, 
The equation for the volume of a cylinder is V = πr²h. 
The first step into finding the radius is to plug in what you already know into the equation:
We divide both sides by 5:
Now we divide both sides by π:
Finally we just do the square root of 49.0197224723:
The radius therefore would be about 7cm. 
Hope I helped,

Answer:
There are 11,355 milliliters in 3 gallons, and 946.25 milliliters in 1 quart.
Step-by-step explanation:
If there are 3,785 milliliters in 1 gallon, multiply each side by 3 because you want the product to equal 3 gallons.3,785 times 3 is equal to 11,355, and 1 times 3 is 3. So, 3 gallons are equal to 11,355 milliliters. If there are 3,785 milliliters in 1 gallon, and there are 4 quarts in 1 gallon, that means that there are 3,785 milliliters in 4 quarts. Now, you want to find the amount of milliliters in 1 quart so you should divide both the 3,785 and the 4 by 4. So, there are 946.25 milliliters in 1 quart.
 
        
                    
             
        
        
        
Answer:
12
Step-by-step explanation:
This value would be 2(-1)^2*2(3).  I have enclosed the given values of x and y for clarity.
This works out to 2(1)*2(3) = 12.
