For this case we have the following equations:
 2x - 3y = 1
 2x + 3y = 2
 When adding both equations we observe that:
 Sentence 1: we have an equation of a variable, which in this case will be x. We can clear the value of x.
 Sentence 2: Knowing the value of x, we can substitute in any equation and find the value of y.
 Sentence 3: The value of x and y represents the point of intersection of both lines (x, y).
        
             
        
        
        
Answer:
No.
Step-by-step explanation:
Well, is the points (1, -9) does satisfy the equation y = 3x - 6. Then, substituting the values of x, and, y, into the equation y = 3x - 6,  we should get a true equation.
y = 3x - 6
-9 = 3 * 1 - 6
-9 = 3 - 6
-9 = -3.
So, the points (1, -9) does not satisfy the equation y = 3x - 6.
 
        
             
        
        
        
Answer:
circumference of a circle = 2*pi*radius
just multiply 3.14 (pi) by 2 by the radius/diameter divided by 2
 
        
             
        
        
        
Answer:
Amount of frozen soup = 2500 mL
Step-by-step explanation:
We are told that tom made 5,000 mL of soup. 
We are also told he packed 2.5 Litres into his kids' lunches. 
Now, from conversions, 
1 liter = 1000 mL
Thus, 
2.5 litres = 2.5 × 1000 = 2500 mL
Now, we are told he froze the rest of the soup. 
Thus;
Amount of frozen soup = total amount of soup made - amount given to kids' lunch pack. 
Amount of frozen soup = 
5000 - 2500 = 2500 ml
 
        
             
        
        
        
<u>Answer:</u>
Lin: 25 × 8,2 =<em> 205 meters</em>
Elena: 250 ÷ 28 = <em>8,9 meters per second</em>
Diego: 32 × (-8,1) = <em>-250,2 meters</em>
Andre: -258 ÷ 25 = <em>-10,32 meters per second </em>
