Average movie prices in the United States, in general, lower than in other countries. It would cost $77.45 to buy three tickets in Japan plus two tickets in Switzerland. Three tickets in Switzerland plus two tickets in Japan would cost would cost $73.65. How much does an average movie ticket cost in each of these countries?

17.01, 13.21

Step-by-step explanation:

j = Japan, s = Switzerland

Make the 2 equations

3j + 2s = 77.45     2j + 3s = 73.65

Multiply the first equation by 2 and the second by 3 so the x values are the same

6j + 4s = 154.90    6j + 9s = 220.95

Now subtract the 2 equations:

  6j + 9s = 220.95

-  6j + 4s = 154.90

5s = 66.05

s = 13.21   Price of tickets in Switzerland

Now replace s with 13.21 into one of the equations

3j + 2(13.21) = 77.45

3j + 26.42 = 77.45

3j = 51.03

j = 17.01 Price of tickets in Japan

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
