We are told that circle C has center (-4, 6) and a radius of 2.
We are told that circle D has center (6, -2) and a radius of 4.
If we move circle C's center ten units to the right and eight units down, the new center would be at (-4 + 10), (6 - 8) = (6, -2). So step 1 in the informal proof checks out - the centers are the same (which is the definition of concentric) and the shifts are right.
Let's look at our circles. Circle C has a radius of 2 and is inside circle D, whose radius is 4. Between Circle C and Circle D, the radii have a 1:2 ratio, as seen below:

If we dilate circle C by a factor of 2, it means we are expanding it and doubling it. Our circle has that 1:2 ratio, and doubling both sides gives us 2:4. The second step checks out.
Translated objects (or those that you shift) can be congruent, and dilated objects are used with similarity (where you stretch and squeeze). The third step checks out.
Thus, the argument is correct and the last choice is best.
Answer:
$3714.18
Step-by-step explanation:
From the question;
Amount invested is $3300
Rate of interest 3% per year compound interest
Time is 4 years
We want to determine the amount that accrued after 4 years
In this case we are going to use the compound interest formula;
That is;
where A is the amount, P is the principal , r is the rate of interest and n is the time taken.
Therefore;

= $3714.18
Therefore, the amount accrued after 4 years is $3714.18
The are parallel to each other because the are both straight horizontal lines
Answer:
[x-3] [x+4]
Step-by-step explanation:
You look to see if you spot the appropriate factors strait away. If you can not immediately determine them you have to consider all of the potential ones and reason out which ones work.
