Answer: The answer is (b) A is subset of B.
Step-by-step explanation: Two sets A and B are given as follows -
A = {1, 2, 3} and B = {3, 2, 1}.
The given options are
(i) 4 ∈ A. This is not correct, since 4 is a not in the set A.
(ii) A is a subset of B. This option is correct since every element of set A is in set B.
(iii) A is an infinite set. This is also not correct, since A has only 3 elements, so it is a finite set.
(iv) Since option (ii) is correct, so this option is incorrect.
Thus, the correct option is (ii) A is subset of B.
Answer:
The solution is similar to the 2-point form of the equation for a line:
y = (y2 -y1)/(x2 -x1)·x + (y1) -(x1)(y2 -y1)/(x2 -x1)
Step-by-step explanation:
Using the two points, write two equations in the unknowns of the equation of the line.
For example, you can use the equation ...
y = mx + b
Then for the points (x1, y1) and (x2, y2) you have two equations in m and b:
b + (x1)m = (y1)
b + (x2)m = (y2)
The corresponding augmented matrix for this system is ...
![\left[\begin{array}{cc|c}1&x1&y1\\1&x2&y2\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D1%26x1%26y1%5C%5C1%26x2%26y2%5Cend%7Barray%7D%5Cright%5D)
____
The "b" variable can be eliminated by subtracting the first equation from the second. This puts a 0 in row 2 column 1 of the matrix, per <em>Gaussian Elimination</em>.
0 + (x2 -x1)m = (y2 -y1)
Dividing by the value in row 2 column 2 gives you the value of m:
m = (y2 -y1)/(x2 -x1)
This value can be substituted into either equation to find the value of b.
b = (y1) -(x1)(y2 -y1)/(x2 -x1) . . . . . substituting for m in the first equation

Answer B
Step-by-step explanation:
I did it and got 63.19
The value of 29 - |7 - 11| = 25
We have the following expression -
29 - |7 - 11|
We have to find its value.
<h3>Find the value of the expression -</h3><h3>X + |

Y | where Y < 0</h3>
We have -
X + |
Y |
Since Y < 0 - therefore
Y < 0
Now -
|a| = - a { for a < 0}
Therefore -
X -
Y
According to the question, we have -
29 - |7 - 11|
29 - | -4 |
29 - 4
25
Hence, the value of 29 - |7 - 11| = 25
