Answer:
regular price = $15
Step-by-step explanation:
Represent the regular price by d.  Then the discount was 0.20d, and the sale price was (1 - 0.20)d, or 0.80d, which is $12.
Solving for d, we divide both sides by 0.80:
d = regular price = $15

Answer:
  (-2x - 1) • (x + 3)
Step-by-step explanation:
3.2     Factoring  2x2 + 7x + 3 
The first term is,  2x2  its coefficient is  2 .
The middle term is,  +7x  its coefficient is  7 .
The last term, "the constant", is  +3 
Step-1 : Multiply the coefficient of the first term by the constant   2 • 3 = 6 
Step-2 : Find two factors of  6  whose sum equals the coefficient of the middle term, which is   7 .
      -6    +    -1    =    -7	
      -3    +    -2    =    -5	
      -2    +    -3    =    -5	
      -1    +    -6    =    -7	
      1    +    6    =    7    That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  1  and  6 
                     2x2 + 1x + 6x + 3
Step-4 : Add up the first 2 terms, pulling out like factors :
                    x • (2x+1)
              Add up the last 2 terms, pulling out common factors :
                    3 • (2x+1)
Step-5 : Add up the four terms of step 4 :
                    (x+3)  •  (2x+1)
             Which is the desired factorization
 
        
             
        
        
        
we know that
The vertex of the graph  is the point
  is the point 
The vertex of the graph  is the point
  is the point 
so
the rule of the translation is

That means
one unit to the left
therefore
<u>the answer is the option </u>
1 unit left
