Answer:
vertical asymptote at x=2 and x=-1
Step-by-step explanation:
To find out vertical asymptote we set the denominator =0 and solve for x
now factor left hand side
find out two factors whose product is -2 and sum is -1
-2 times 1 = -2
-2+1 = -1
(x-2)(x+1) =0
x-2 =0 so x= 2
x+1 =0 so x=-1
vertical asymptote at x=2 and x=-1
Answer:
Step-by-step explanation:
Let r represent speed in the carpool.
We have been given that on the way to work Juan carpools with a fellow co-worker then takes the city bus back home in the evening. The average speed of the 20-mile trip is 5 miles per hour faster in the carpool.
We know that time is equal to distance over speed.
The total distance is 20 mile. Time taken to travel 20 miles using carpool would be
The speed on the bus is 5 miles greater, so it will be . Time taken to travel 20 miles using bus would be
Total time will be equal to sum of both times that is:
Let us simplify our expression.
Combine numerator:
Therefore, our required expression would be .
