Suppose you run a business that develops Web sites for e-commerce. You charge a flat fee of $2,700 to create the Web site. One of your clients also pays you a $15 bonus for every seven people who visit the site. How many people need to visit the Web site in order for you to match your fee for creating the Web site? Write an equation and solve it.

The 4 equations that equals 16 will be , , and .

In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equal sign "=".

Equations often contain algebra. Algebra is used in Math when you do not know the exact number in a calculation.

But, in given question, there is no variable in the statement so we use only constant to make equation which is equal to 4.

Now the equation will be,

To Euclid, a postulate is something that is so obvious it may be accepted without proof.

A. A straightedge and compass can be used to create any figure.

That's not Euclid, that's just goofy.

B. A straight line segment can be drawn between any two points.

That's Euclid's first postulate.

C. Any straight line segment can be extended indefinitely.

That's Euclid's second postulate.

D. The angles of a triangle always add up to 180.

That's true, but a theorem not a postulate. Euclid and the Greeks didn't really use degree angle measurements like we do. They didn't really trust them, I think justifiably. Euclid called 180 degrees "two right angles."

Answer: B C

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}.

1. 4y > 20

4y / 4 > 20 / 4

y > 5

2. 7x + 21 < -28

7 < -28 - 21

7x < -49

x < -7

3. -12m - 24 > 36

-12m > 36 + 24

-12m > 60

m < - 5

hope this helped :)
