<span>Use the Pythagorean Theorem to solve. This will be a right triangle:
=
Let the slope = the hypotenuse = c
Let one side = a=8
Let the other side =b =15
Plug-in the values and solve for the c-term
Check you answer by plugging the value of "c" back into the orignial equation and solve.

17=c
.
Check by plugging into the original equation and solve.

Hello!
The correct answer is A translation 3 units up then a reflection across the x-axis.
Translation: moving/sliding a figure
Reflection: taking a figure and flipping it over a line.
First you multiply 3 x 1000 which is 3,000. Then you too 2 x 100 which is 200. Lastly you subtract 3000 from 200 and you get 2800.
We know that they have:
2 entrences
3 ways to chose (escalator,elevator and stairs)
8 gates
and again 3 ways to chose (escalator, elevator and stairway)
now you have to multiply it:

There are 144 different ways that Anita and Terry can go from street level to the trains:)
=(0.4n)(16n)
multiply 0.4 & 16 and n & n
=(0.4*16)(n * n)
=6.4n^2
Hope this helps! :)
