Answer:

D. y = 12.5x + 15

Step-by-step explanation:

Using the values provided in the table, the only equation that would be valid would be the following...

y = 12.5x + 15

That is because if we substitute any value provided in the table for x , this equation will correctly output the y value shown in the table for the attached x-value. For example, in the table 5 nights (x = 5) should have a total cost of 77.5 (y = 77.5)... Therefore, if we substitute 5 for x in the function it should give  us 77.5 which it does.

y = 12.5(5) + 15

y = 62.5 + 15

y = 77.5

I need to write an even number between 7 and 16 draw a picture an them write a sentence to explain why it is an even number
serious [3.7K]
An even  number is a number that is divisible by 2.
This means that dividing this number by 2 yields no remainder (the remainder is zero).

The even numbers between 7 and 16 are:
8 as 8/2 = 4 and remainder is zero
10 as 10/2 = 5 and remainder is zero
12 as 12/2 = 6 and remainder is zero
14 as 14/2 = 7 and remainder is zero

What is the 2nd term when −3f3 + 9f + 6f4 − 2f2 is arranged in descending order?
Brilliant_brown [7]

For this case we have the following polynomial:

-3f ^ 3 + 9f + 6f ^ 4 - 2f ^ 2

To answer the question, what we must do is rewrite the polynomial in its standard form.

We have then that the polynomial will be given by:

6f ^ 4 - 3f ^ 3 - 2f ^ 2 + 9f

Therefore, we have the ordered polynomial in descending form of exponents.

Therefore, the second term of the polynomial is:

- 3f ^ 3

Answer:

The second term of the polynomial is given by:

- 3f ^ 3

The conclusion is:   "n is divisible by five."

The converse is:   "If n is divisible by five, the the last digit of n is zero."

The contrapositive is:   "If n is not divisble by five, then n does not end in zero."

Step-by-step explanation:

I just took the test :)
