Answer:
C
Step-by-step explanation:
(a)
2 : 4 ( divide both values by 2)
= 1 : 2
3 : 6 ( divide both values by 3 )
= 1 : 2
Thus 2 : 4 = 3 : 6
(b)
3 : 9 ( divide both values by 3 )
= 1 : 3
Thus 1 : 3 = 3 : 9
(c)
4 : 6 ( divide both values by 2 )
= 2 : 3 ≠ 3 : 2
(d)
10 : 2 ( divide both values by 2 )
= 5 : 1
Thus 5 : 1 = 10 : 2
I think it is a D I'm not really sure
The value is the tens place
Y = -2x
because every point of the rhombus vertex will reflect on the opposite vertex.
Answer:
20
Step-by-step explanation:
because f (20) would also be 20. Since we don't know the value behind 20, we would suppose x is the value. The original equation is now 
. If we do 
we would get that (since x is being substituted) 
.
