Answer:
nr. 1 and 3 is a Dilation 2 and 4 are not Dilations
Step-by-step explanation:
Dilation is an elnargment or shink of a figure by a x(factor) that makes the SAME image but smaller or larger

Divide both the numerator and denominator by 9 to get;

Convert the improper fraction to a mixed number;
Using it's concept, it is found that the domain for the expressions is, respectively, given by:

<h3>What is the domain of a function?</h3>
It is the <u>set that contains all possible input values</u>.
In a fraction, the denominator cannot be zero, hence:
- The domain of the first two expressions is of
.
- The domain of the last expression is of
.
The third expression can be simplified, as:
(x + 5)/(x + 5) = 1.
The same is true for the fourth, as:
x²/x = 1.
Neither has any restriction, hence their domain is all real numbers, represented by
.

Answer:
The probability is 169/2652
Step-by-step explanation:
The number of cards in a deck of cards is 52
In each deck of cards, there are 13 black cards and 13 spade cards
The probability of selecting a spade card will be;
13/52 = 1/4
Without replacement, we are left with 51 cards and the probability of selecting a black card will now be 13/51
So the probability of the second card being a black card if the first is spade will be ;
13/52 * 13/51
= 169/2,652
