Answer:
It means the left side of the equation equals the right side of the equation regardless of the value of the variables. The solution is all real numbers for each variable

<u><em>Answer:</em></u>18
<u><em>Explanation:</em></u>To round a number to the nearest whole number, we would check the fraction part:
If the fraction is <u>less than</u> 0.5, then we would simply ignore the fraction
If the fraction is <u>equal to or more than </u>0.5, then we would add 1 to the whole number and eliminate the fraction.
<u>In the given , we have:</u></span>

<span>. 
The fraction part is </span>

<span> which is greater than 0.5
This means that we would add one to the whole number (round it up) and eliminate the fraction.
Therefore, the answer would be 18.
Hope this helps :)</span>
 
        
        
        
7 girls participated only in Karate.
21 + 8 = 29
29 + 7 = 36
36 + 6 = 43
        
                    
             
        
        
        
In order to visualize the transformations, we must execute the transformation in the options
The first transformation would shift triangle ABC 3 units to the left and reflect it across x = 4. This will not map ABC unto DEF.
The second transformation would shift triangle ABC 7 units down and reflect it across x =4. This will map ABC unto DEF,
So, the answer is the second option.
