Answer:
A'B' = 34 units
Step-by-step explanation:
Since the dilatation is centred at the origin , then multiply the coordinates by 2
A' = (2(0), 2(- 7) = (0, - 14 )
B' = (2(8), 2(8) = (16, 16)
Calculate the length using the distance formula
d = 
with (x₁, y₁ ) = A'(0, - 14) and (x₂, y₂ ) = B'(16, 16)
d = 
= 
= 
= 
= 34
Answer: the rule is (x, y) → (x – 4, y + 15)
D’ in the image are (9, –8)?
x – 4= 9 y + 15= -8, so x=13, and y = - 8-15=-23
so D(13, -23)
Answer:
The given equation is
y =
x
→ 
reciprocating both sides, we get
→ 
............(1)
→ Here x and y are Directly proportional to each other.
which means ,
→ x = k y , where k is constant of proportionality.
Or , 
= k ............................(2)
Equating (1) and (2),
k =
