Answer:
The train need to leave Portland at 03:27 am
Step-by-step explanation:
step 1
Find out how long it takes the train to travel from Portland, Oregon, to Los Angeles, California
Remember that
The speed is equal to divide the distance by the time
so
The time is equal to divide the distance by the speed
Let
s ---> the speed in miles per hour
d ---> the distance in miles
t ---> the time in hours
we have
substitute
step 2
Adds 30 minutes (time it takes to get from the train station to her aunt's house)
Remember that
Convert to minutes
step 3
Remember that
Convert to minutes
Subtract 993 minutes from 1,200 minutes
Convert to hours+minutes
so
therefore
The train need to leave Portland at 03:27 am
So, the questions is 6^(-6) * 6^(-1).
Remember, whenever we are multiplying two numbers with the same base and with different exponents, we should always add the exponents and keeps the same base.
In this ,case it is, -6 and -1.
-6 + (-1) = -7
So the answer would be 6^(-7).

Answer:
I got, when calculated, 209 miles. (It may be wrong)
Step-by-step explanation:
First, I calculated how many miles can Sandeep travel with 1L, therefore I divided 76 miles by 8L and got 9.5 miles on 1L.
Then I multiplied 9.2 miles by 22L and got 209 miles.
This may be wrong but if anyone else is able to work it out much appreciated if it's correct.. Your most welcome!
13x-88 ≤ -32
there's your answer
Ƒ(x) = 2x and g(x) = 3x?
The question means at which points (or coordinates) f(x) & g(x) intercepts.
In this case you proceed as follows:
f(x) =g(x)==> 2x = 3x or 0 = x if x = 0 , y also =0 then both graphes passes through the origin O (0,0)
