C. Yes, because all the rations of y to x are equal to 3 (: hope this helps
Answer:
4³
Step-by-step explanation:
16 x 4
(4 x 4) x 4 = 64
Since they want only the coordinates of the vertices. You only care about where the lines intersect, the greater than, less than signs are irrelevant.
Get each equation in 'y=mx+b' form
1) y = -x + 9
2) y = 2x-21
3) y = -4x +15
Now you can set any 2 equations equal to each other and solve for 'x'.
This will be the 'x' coordinate of the point where the 2 lines intersect.
You need 3 points, so you will need 3 different sets of 2 equations:
1) = 2)
2x -21 = -x+9
3x = 30
x = 10 -----> y = -(10)+9 = -1
1) = 3)
-x+9 = -4x+15
3x = 6
x = 2 -------> y = -(2) + 9 = 7
2) = 3)
2x - 21 = -4x+15
6x = 36
x = 6 ---------> y = 2(6) -21 = -9
Therefore the 3 intersecting points are:
(10,-1)
(2, 7)
(6, -9)
Time of the 20 to the x then get 420
is the factored form of given polynomial 
<em><u>Solution:</u></em>
Given that we have to factor the given polynomial
Factoring: Finding what to multiply together to get an expression. It is like "splitting" an expression into a multiplication of simpler expressions.
<em>Factoring a polynomial involves writing it as a product of two or more polynomials</em>
Given polynomial is:
Step 1 :
We can use factoring by grouping
Group 
with 3xy and −12y with 9x then factor each group.
Taking -y as common term from first two terms and -3 as common term from last two terms
Now taking (4y - 3x) as common term
So the given polynomial is factored
