Answer:
3rd option
Step-by-step explanation:
Since the centre of dilatation is at the origin then multiply the coordinates by 
K (- 3, 9 ) → K' (- 3(
), 9(
) ) → K' (- 1, 3 )
L (- 9, 0 ) → L' (- 9(
), 0 (
) ) → L' (- 3, 0 )
M (2, - 8 ) → M' (2 (
), - 8 (
) ) → M' (
, -
)
N (6, 4 ) → N' (6 (
) , 4 (
) ) → N' ( 2,
)
Answer:
I used the answer the other person gave, but it said it was wrong. Here was the answer I put in the second time.
Step-by-step explanation:
Answer:
b=2.5
Step-by-step explanation:
every point on x axis has y coordinate =0
so bx=10
x=4
4b=10
b=10/4=5/2=2.5
The answer is 301 , because 73 times 4=292 .
292 + 9=301
