N x 2 = 12 + 5n
2n - 5n = 12
-3n = 12
3n = -12
n = -4

Answer:
Step-by-step explanation:
3/4 x 28=21   Madilyn built 21 toys.
1/7 x 28=4     Penelope built 4 toys.
21+4=25        25 toys have been built altogether.
28-25=3
There are 3 toys left to build.
 
        
             
        
        
        
The result of an absolute value operation is never negative. So the smallest that the expression |x+5| can be is 0. 
Tacking on "-8" to |x+5| leads to |x+5|-8
The range of this is [-8, infinity) since the smallest |x+5|-8 can be is -8. All I did was subtract 8 from the smallest value of |x+5|
Final Answer: choice C)
        
             
        
        
        
Answer:
<h2>There are needed 3 burgers to reach the maximum measure of happiness of 25.</h2>
Step-by-step explanation:
The given function is

Where  is the number of burgers and
 is the number of burgers and  the measure of happiness.
 the measure of happiness.
To find the maximum burgers needed to reach the maximum happiness, we just need to find the vertex of this function, which is defined as
 where
 where  , and
, and  ,
,  , replacing these values, we have
, replacing these values, we have
