They are not similar because BR: DB is 1:2 and KE:YK is 1:3. This is due because of the slope, the slope of KE:YK is 9/3 or 3/9 which is equal to 1:3 and the slope for BR:DB is 2/4 or 4/2 which is how you get the ratio of 1:2.
The number of complex roots is 2 or 0
Answer:
The value of x is 12
Step-by-step explanation:
4x3=12
7x3=21
Therefore 12/21
To explain further:
If you divide 12 by 3 you get 4
If you divide 21 by 3 you get 7
Therefore resulting to 4/7
(I found out that the number three goes in both numbers to begin with)
Is this clearer?
Answer:
i don't know this i think its 3.4 or 1.9
K=slope
b=y intercept
find slope
slope=(y2-y1)/(x2-x1)
(x,y)
(1,-2)
(-2,-8)
x1=1
y1=-2
x2=-2
y2=-8
slope=(-8-(-2))/(-2-1)=(-6)/(-3)=2/1=2
k=2
subsitute
y=2x+b
subsitute one point
(1,-2)
x=1,y=-2
-2=2(1)+b
-2=2+b
subtract 2
-4=b
y=2x-4
