For this exercise you must remember that the original figure (before a transformation) is called "Pre-Image" and the one obtained after the transformation is called "Image".

Dilation is defined as a transformation in which the Image and the Pre-Image have the same shape, but different sizes.

If a figure is dilated by a scale factor "k" with respect to the origin, the rule is:

$(x,y)$ → $(kx,ky)$

In this case, the vertices of the triangle JKL (the Pre-Image) are:

$J(-3.2)\\\\K(3,2)\\\\L(0,-4)$

Knowing that the scale factor is:

$k=5$

You get that the vertices of the triangle J'K'L' (Image), are:

$J'=(5(-3),5(2))=(-15,10)\\\\K'=(5(3),5(2))=(15,10)\\\\L'=(5(0),5(-4))=(0,-20)$

The first option is correct.

Step-by-step explanation:

how do we multiply x - 9 by something? we put it in brackets

(x - 9) × (-3) = 51

that can be written like this

The ratio of the areas of corresponding faces of two cubes is 1:16. what is the ratio of their volumes?

Yakvenalex [24]

The ratio of the areas is the one-to-one measure squared. In order to find the ratio of their volumes, which is a cubed measure, we have to find the one-to-one and them cube it. The square root of 1/16 is 1/4. Now if we cube 1/4 to get the volume, it will be 1/64.
