Answer:
The correct answer is D. 360,360.
Step-by-step explanation:
Number of cities as stopovers available for selection for an European tour = 15
A traveler has to select a total of five cities from these the given 15 cities for his tour and order is determined by the travel company.
Therefore the number of ways the traveler plan such a tour is given by = 3003.
Now the order of the cities chosen by the travel company is given by 3003 × 5! = 360,360 ways.
Answer:
d) intersecting, but not perpendicular lines
Step-by-step explanation:
Changing the sign of one of the variable terms causes the line to be reflected across one of the axes. The slope is the opposite of what it was. Since the original slope was not 1 or -1, the resulting line is not perpendicular to it. Lines with different slopes will be intersecting.
The two lines are intersecting, but not perpendicular.
The answer is the last option:
Explanation:
1. You have that the equation of the line is:
Where is the slope of the line and
is the intercept with the y-axis.
2. Therefore, you must find .
3. Then, you must substitute the points given in the problem and the slope into the equation of the line and solve for , as following:
