The coordinates of triangle QRS are Q(-2, 4), R14,0) and S(6,2). The figure was dilated and the new coordinates are Q(-3, 6), R'(6,0) and S'(9,3). What is the scale factor? What is the algebraic rule?​

Scale factor is 3/2

Step-by-step explanation:

Just take any coordinate of any point that was scaled and that had a non-zero initial value. Let’s take the x axis of Q. There’s .

So, the scaling factor has to be . You can confirm that . (I omitted because of zero values)

The algebraic rule for getting the point in the dilated space from any given point is

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
