△q′r′s′ is the image of △qrs under a dilation through point c. what scale factor was used in the dilation? −4 −0.25 0.25 4

The scale factor was used in the dilation = -4

Step-by-step explanation:

From the given picture, the length of side SR in pre-image = 3cm

The length of corresponding side S'R' in image = 12 cm

Then , the scale factor of dilation will be :-

Since , the enlargement appearing on the other side , then the scale factor becomes negative.

Hence, the scale factor of this dilation =-4.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
