Answer:
1. 6798 7657 6541 9068.
2. 7658 9864 2076 9866.
3. and domain of f(x) is {0,1,2,3,4,5,6,7,8,9}.
4. and domain of f⁻¹(x) is {0,1,2,3,4,5,6,7,8,9}.
We are given that,
The coding method for the card number is 'Subtract each digit from 9'.
So, we have,
Part 1: The number given is 3201 2342 3458 0931.
So, after subtracting each digit from 9, we have,
The coded number is 6798 7657 6541 9068.
Part 2: The coded number given is 2341 0135 7923 0133.
To find the original number, we will subtract the digits from 9.
The original number is 7658 9864 2076 9866.
Part 3: We have f(x), where x represents the single input digit.
That is, 'x' can have values from {0,1,2,3,4,5,6,7,8,9}.
As, the coded output is the number subtracted from 9.
We get, the function is.
So, the domain of f(x) is {0,1,2,3,4,5,6,7,8,9}.
Part 4: We need to find the inverse function.
So, we have, i.e.
.
Thus, the inverse function is
Since, the range of f(x) is the domain of f⁻¹(x).
The domain of f⁻¹(x) is {0,1,2,3,4,5,6,7,8,9}.

The area of a triangle is found by using the formula;
A=1/2bh where A is area, b is base and h the height
substituting for given values;
12 2/5=1/2*3 1/4*h
Rewriting the values as improper fractions;
62/5=1/2*13/4*h
62/5=13/8h
h=62/5 *8/13
h=496/65
h= 7 41/65 units

The correct answer is:
It is helpful to round to the hundredths when we are dealing with money.
Explanation:
Our monetary system has dollars and cents, and it takes 100 cents to make a dollar. This means we would have a measurement to the hundredth place for money. If we are dividing and get a quotient that goes past the hundredths place, if it is money, we should round it to the hundredths place.

8 would be C m = -1/2
If a line is parallel, then the slop is the same. If it is perpendicular, the it will be the opposite sign and the reciprocal. So parallel would be 2 and perpendicular would be -1/2
