Answer:
C. 7 hours
Step-by-step explanation:
Let the time for the trip out be represented by t. Then the time for the return trip is t-1. The distance was the same for both trips, so we have ...
distance = speed × time
300t = 350(t -1)
300t = 350t -350 . . . . eliminate parentheses
350 = 50t . . . . . . . . . . add 350-300t
7 = t . . . . . . divide by 50
The trip out took 7 hours.
Answer:
See below
Step-by-step explanation:
a. here you are to multiply the two functions together:
b. here you are to subtract g from f:
c. here you are to compose g into f. In other words, pick up the whole g function and plug it into f wherever you see an x:
d. here you are compose f into g. In other words, pick up the whole f function and plug it into g wherever you see an x:
You now have to FOIL out the (3x-1) like so:
which gives you
Distribute in the 2 and you'll end up with the answer:
Step-by-step explanation:
3/5 is the probability answer
Answer:
3
Step-by-step explain:
when you think of median, think of middle, the middle of those numbers is 3. When you have a even number of values for example i have 6 values and i have to find the median. I would look at the 2 middle numbers and come up with my median.
Answer:
a²(b² - 2b) = a²b² - 2a²b
- a²(b² - 2b) is odd but -2a²b is the even number
=> a²b² must be the odd (because an odd number minus an even number equals an odd number)
=> a and b are odd (proven)
