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
<u>Answer:</u>
Helen's salary increased more.
<u>Step-by-step explanation:</u>
We know that Clint's salary increased from $24000 to $36000 over a three-year period.
So the increase in Clint's salary will be = 36000 - 24000 = $12000
While Helen's salary increased from $29000 to $43, 500 over the same period of 3 years.
So the increase in Helen's salary will be = 43500 - 29000 = $14500
Therefore, in absolute terms, Helen's salary has increased more.
Answer would be 9/6,but can be simplified to 3/2
