Since you're told that the airfare cost is 737 we know that this is a number that will not be varied in any way and that this number will be added to the number of nights that he pays for to stay at a hotel. We are also told that the cost per night is 164 and that x represents the number of nights that he stays. We can then have the following

y = 164x + 737

for the second package we are told that it cost 249 for the round trip and 531 per night at a hotel. Moreover, once again x represents the number of nights that he will be staying at the hotel, giving the equation

y = 531x + 249

therefore, option C is the correct answer.

enrollment in a photography class increased from 25 to 35 students. What was the percent of increase in enrollment?
ElenaW [278]

<u>Answer</u>

40%

<u>Explanation</u>

A parentage value is a value that has been compared to 100.

Percentage = (change in the value)/(the original value) × 100%

                   = (35-25)/25 × 100%

                    = 10/25 × 100%

                   = 40%

2m=-6n-5 literal equation
Bingel [31]

Answer:

read below

Step-by-step explanation:

Alright, archtan /  

tan

−

1

(

x

)

is the inverse of tangent. Tan is  

sin

cos

. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4.

Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan(-1) equal. Using the unit circle we can see that tan(1)= pi/4.

Since the "Odds and Evens Identity" states that tan(-x) = -tan(x). Tan(-1)= -pi/4.

Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.

the answer is m=-3n-5/2 or n=2m+5/6
