Answer:
B. The other solution to function 
is 
.
Step-by-step explanation:
From Algebra, we remember that quadratic functions of the form 
has solutions of the form:
, where both are complex if and only if 
.
Hence, if one solution of the quadratic function is 
, then the other solution is . The correct answer is B.
216 as when 2 there is 6x6 but when there’s 3 it’s 6x6x6 which is 216
The two rectangles are similar and the scale factor is 3:4
Answer: Add 2 to each side
Step-by-step explanation:
9m-2=16
+2 +2
9m=18
Where <em>x </em>is the number of books sold, <em>i </em>is income, and <em>c </em>is cost:
<em>c = 4x + 3500 </em> ($4 per book plus the 3500 flat marketing fee)
<em>i = 15x </em>($15 per book)
You are looking for the point where these intersect: the intersection is where the income is equal to the cost, and at any point after that the income is greater than the cost. So, set the equations equal to each other:
<em>4x + 3500 = 15x </em>
subtract 4x from both sides
<em>3500 = 11x</em>
divide both sides by 11
<em>x = 318.181818</em>
So, you would have to sell a minimum of 319 books in order to make a profit.
