Answer: The scale factor of the dilation =3


Step-by-step explanation:

We know that if we transform point (x,y) by using dilation with scale factor k then the coordinate of the image will be (kx,ky).

Given: under a dilation, the point (2, 6) is moved to (6, 18)

Here (x,y)=(2,6) and (kx,ky)=(6,18)

\\\Rightarrow\ x=2\ and\ kx=6\\\Rightarrow\ k(2)=6\\\Rightarrow\ k=3

Hence, the scale factor for the given dilation= 3.

If point U is reflected across the x = −3, what are the coordinates of its reflection image?
oee [108]

Answer:

The coordinates of the image point will be [-(h + 6), k].

Step-by-step explanation:

Let the original point U has the coordinates (h,k).

Now, if point U reflects across the line x = - 3 line, which is parallel to the y-axis, then the only x-coordinate of the image point change but the y-coordinate will remains the same.

Now, the distance from line x = - 3 to the point U is (3 + h).

Hence, the distance of the image point is (3 + h) horizontally from the line x = - 3.

So, the distance of the image point from the y-axis will be [(h + 3) + 3] = h + 6

Therefore, the coordinates of the image point will be [-(h + 6), k]. (Answer)

20 is what percent of 100
Gemiola [76]
20 would be 20% of 100.

Just like 67.67 would be 67.67% of 100.
