Answer:
In Japan a movie ticket has a price of 17.99, and in Switzerland has a price of 13.49.
Step-by-step explanation:
Step 1.
- <em>Let x be the price of a movie ticket in Japan</em>
- <em>Let y be the price of a movie ticket in Switzerland</em>
Step 2.
According with the description:
, (<em>It would cost 80.95 to buy three tickets in Japan + two tickets in Switzerland</em>).
, (<em>Three tickets in Switzerland + two tickets in Japan would cost 76.45</em>).
Step 3.
<em>The two equations of step 2 can be used to solve both x and y</em>. From the first equation, <em>solving x</em>:
.
Step 4.
<em>Replacing x in the second equation</em>:
.
Solving for y (price in Switzerland):
Step 5.
Using the found value of y to solve for x (price in Japan):
Step 6.
Then it is possible to check that:
If both of those times were on the same date and in
the same time-zone, then exactly 1 hour passed.
Answer:
The answer is 0.
Step-by-step explanation:
Simply plug in -7 for x as they want to see what the value of the function is when x=-7.
You can then just add -7 and 7.
7 + -7 = 0
So the answer is 0
First solve the equation by dividing 5 on both sides...
Y = 5\2x + 2
Now we want perpendicular and the line to flip across the axis so the answer is....
Y = -2\5 + 2
