Answer:
B. -1
Step-by-step explanation:
x^3-4x^2+2x+10=x^2-5x-3
We know it has 3 roots since it is a 3rd degree polynomial.
Two of the roots are (3+2i) and (3-2i)
Subtract x^2-5x-3 from both sides
x^3-4x^2+2x+10-(x^2-5x-3)=x^2-5x-3 -(x^2-5x-3)
Distribute the minus sign
x^3-4x^2+2x+10-x^2+5x+3=x^2-5x-3 -x^2+5x+3
x^3 -5x^2+7x +13 =0
Graphing this equation , we see that it crosses the x axis at x=-1
That covers the three roots, 1 real and two complex
Equations can be solved in several ways; one of these ways is the graphical method.
The number of commercials, x, and the number of movies, y, on which Naomi's songs were played are 5 and 2, respectively.
Let:
<em />
<em> commercials</em>
<em />
<em> movies</em>
<em />
She earned a total of $300.
This is represented as:

Her songs were played on 3 more commercials than movies.
This is represented as:

See attachment for the graphs of


From the graph, the lines of both equations intersect at:


This means that:
- <em>The number of movies is 2</em>
- <em>The number of commercials is 5</em>

5× 10= 50
5+5+5+5+5+5+5+5+5=50
5/50 = 1/10 is the fraction in simplest form.
