Solve for any of the variables; for instance, 
:
Then
Let 
; then the intersection is given by the vector-valued function
or
Answer:
Gah! Inverses!
Step-by-step explanation:
This is a pretty simple concept, just switch the x and f(x) values!
If you don't understand, look at how I solve it!
Switching the positions of the x and f(x) values...
Note: That f(x)^-1 is the proper notation for inverse functions.
There you go!
Hope this helps, and don't procrastinate!
Answer:
yes, 0 is a rational number. zero can be represented as p/q in the form of 0/1, 0/2, 0/3, 0/4…etc. since the number zero divided by any number is equal to zero. **and remember rational numbers are numbers that can be written as fractions**
Step-by-step explanation:
0/1=0
0/2=0
0/3=0
0/1000=0
and so on and so forth
**as you can see any number paired with zero will result in 0 being your final answer**
good luck :)
i hope this helps
have a nice day !!
Answer:
1.8 hours.
Step-by-step explanation:
It is important to note that:
Speed = Distance ÷ Time
We have two trains.
Step 1
We have to find the distance that each train travelled.
Since Speed = Distance ÷ Time
Distance = Speed × Time
First train
It travels at 105 miles per hour
Distance travelled by first train =
105 × x hours
= 105x miles
Second Train
It travels at 85 miles per hour
Distance travelled by the second train = 85 miles × x hours
= 85x miles
We are told that: the two trains leave stations 342 miles apart at the same time and travel toward each other
Hence, the time it would take each train to meet each other is calculated as:
105x + 85x = 342 miles
190x = 342 miles
x = 342/190
x = 1.8 hours.
