I think the second choice has the correct domain and ranges
The equation for ten times the sum of half a number and 6 is 8 would be: 10(1/2n+6)=8
Answer:
Step-by-step explanation:
Example:
If E, F, G and H are respectively the mid-points of the sides of a parallelogram ABCD shows that ar ( EFGH) = 1/2 ar ( ABCD)
If E, F, G and H are respectively the mid-points of the sides of a parallelogram ABCD show that ar (EFGH) = 1/2 ar (ABCD)
Given: A parallelogram ABCD where E, F, G, H are the mid-points of AB,BC,CD & AD respectively
To prove: ar (EFGH) = 1/2 ar (ABCD)
Proof: Join H & F
Now,
So, AD || BC ( Opposite sides of parallelogram are parallel)
> DH || CF ( Parts of parallel lines are parallel)
Also, AD = BC ( Opposite sides of parallelogram are equal)
1/2AD = 1/2 BC
DH = CF
( H is mid-point of AD
F is mid-point of BC)
