Answer:

Step-by-step explanation:

$W$ ∩ $X$ is asking for the intersection of sets $W$ and $X$ , or simply, which numbers can be found in both sets.

The numbers shared between the two sets are $3, 4, 5$ .

Next, we need to union this result with the set $Y$ , or simply, combine the numbers in both sets together.

This would result in $2, 3, 4, 5$

F(g(x))= 3(6x+2)-5=18x+6-5=18x+1,
so correct answer is the last one

Transformation that changes the size of a shape is referred to as dilation.

The scale factor that moves the large triangle to the small one is 1/5
The center of dilation is: (-1,1)

<u>The center of dilation</u>

From the diagram (see attachment), the triangles share a common vertex at (-1,1)

This means that, the center of dilation is (-1,1)

<u>The scale factor of dilation</u>

To do this, we divide the side length of the small triangle with the corresponding side of the large triangle.

From the attached image:

$\mathbf{Base\ of\ small\ triangle = 1}$

$\mathbf{Base\ of\ large\ triangle = 5}$

So, the scale factor (k) from large to small is:

$\mathbf{k = \frac{Base\ of\ small\ triangle}{Base\ of\ large\ triangle} }$

$\mathbf{k = \frac{1}{5} }$
