It looks like you have to do distance formula. It's basically this:
D = 
(ignore the A, i dont know how to get rid of it sorry)
I would then plug in the points of A(1,7) and B(10,3).
D = 
Then I would get the square root of 4^2 + 9^2
= square root of 16 + 81
= square root of 97
So the length of AB would be the square root of 97

Answer:
Step-by-step explanation:
The range is the spread of the y-values (minimum to maximum distance travelled).
The graph of your function is a hyperbola shifted two units left and three units up from the origin.
There is a vertical asymptote at x = -2, so y does not exist when x = -2. However,
Since the limit from either side is the same,
The graph below shows the asymptotes of your function.
Thus. y can take any value except 3.
In set builder notation, the range is
Answer:
The time of a commercial airplane is 280 minutes
Step-by-step explanation:
Let
x -----> the speed of a commercial airplane
y ----> the speed of a jet plane
t -----> the time that a jet airplane takes from Vancouver to Regina
we know that
The speed is equal to divide the distance by the time
y=2x ----> equation A
<u><em>The speed of a commercial airplane is equal to</em></u>
x=1,730/(t+140) ----> equation B
<u><em>The speed of a jet airplane is equal to</em></u>
y=1,730/t -----> equation C
substitute equation B and equation C in equation A
1,730/t=2(1,730/(t+140))
Solve for t
1/t=(2/(t+140))
t+140=2t
2t-t=140
t=140 minutes
therefore
The time of a commercial airplane is
t+140=140+140=280 minutes
