The answer would be 400$. This is because 40 x 10 = 400.
800 different sets of digits
Since the first digit is a factor of 20, the factors of 20 are 1,2,4,5,10,20. We only need the single digit factors which are 1,2,4 and 5. These 4 numbers can be permuted in 1 way for the first digit, so we have ⁴P₁.
For the second digit, we have 10 digits permuted in 1 way, ¹⁰P₁ and also for the third digit, we have 10 digits permuted in 1 way, ¹⁰P₁ and for the last digit, which is divisible by 5, it is either a 0 or 5, so we have two digits permuted in 1 way, ²P₁.
So, the number of different 4 digit number that Zara'2 4-digit PIN code could be is ⁴P₁ × ¹⁰P₁ × ¹⁰P₁ × ²P₁ = 4 × 10 × 10 × 2 = 800 different sets of digits
Given:
The number is
.
To find:
The location of the given number of the number line.
Solution:
We have,

It can be written as



It means the number is less than -1 but more than -2. So, the number lies between -2 and -1.
The mixed fraction form of given number is



Divide the number in 5 equal parts between two consecutive integers.
Now each unit represents
.
Since
, therefore, it is 2 units left from -1.
The number line is given below.

Answer:
y=x-2
Step-by-step explanation:
If you have drawn the graph of
.
To determine the equation of the line which should be drawn to solve the equation: x² - 4x +3=0
Simply carry out the subtraction: 

The equation of the line which should be drawn is: y=x-2
What this means is simply:
If
