Answer:
A dilation is a type of transformation that enlarges or reduces a figure to create a new figure, If the scale factor is between 0 and 1 the image is a reduction. If the scale factor is greater than 1, the image is an enlargement
The 20th term is -106
15,9,3,-3,-9,-15,-21,-28,-35,-41,-46 (10) -6 x 10 = -60
-60 + -46
-106
You're just subtracting by 6.
The answer is 4x^2
all you gotta do is multiply them like usually but -
(2X^3.)(2X^-1)
4X^(3-1)=4X^2
if events X and Y are independent, then for intersection we multiply the probability
P(Y∩X) = P(Y) * P(X)
We know that

Now we replace P(Y) * P(X) for P(Y∩X)

Cancel out P(X)
So 
Like that

Now we replace P(X) * P(Y) for P(X∩Y)

Cancel out P(Y)
So 
P(Y | X) = P(Y) and P(X | Y) = P(X) are true
Step-by-step explanation:

then for y:

so:
