Well <span>(x, y)→(−x, y) </span>means it's reflected off the y-axis(You can experiment this with random points on a graph)
(x, y)→(x−1, y+2) means that every point is moved to the left by 1 and up by 2, in other words, the triangle is translated left 1 up 2.
Since the only thing that effects congruency is dilation(rotation, translation, and reflection only move the shape, not change it), The new triangle should equal the old one.
Thus we would get the first choice

What is the best approximation of the length of the radius in a circle with an area of 16pi x in ^ 2 ?
Nutka1998 [239]

Answer:

4in = r

Step-by-step explanation:

Different problem if the x was a variable in the question

formula for area of circle = pi x r^2.

So if the area of a circle is 16 pi in^2, it would be an obvious estimate that the radius is the square root of 16 which is 4 inches.

If the x was a variable, you would find the square root of 16x which is \sqrt{16x} which would make it 4\sqrt{x} as the radius.
