Answer:
Option B
Step-by-step explanation:
Given that the point A(4,6) is dilated with a scale factor of 2
about the point O(2,1) as centre of dilation
This implies that the new point A' will lie on the lineOA with distance equal to double of OA.
Or A will be the mid point of OA' and AA' will have same slope as OA
Considering the above two conditions we find that
Option A cannot be right.
Option B: Midpoint of OA' = (4,6) matches with given
Slope of AA'=
= slope of OA
Thus option B satisfies both
So answer is B

Answer:
491,800!
Step-by-step explanation:
You have to subtract the 6 first and then divide the rest by 1/8.
34-6=28
28×1/8=224
