Answer:
p is perpendicular to n. Proved.
Step-by-step explanation:
See the diagram attached.
Let us assume that mm' and nn' are two straight lines parallel to each other and pp' is a transversal.
It is given that pp' is perpendicular to mm' i.e. ∠po'm = 90°
Now, since mm'║nn' and pp' is a transversal, so, ∠pon = ∠po'm = 90° {Those are corresponding angles}
So, pp' is also perpendicular to nn'. {Proved}

Answer:
Step-by-step explanation:
Let a and s represent the prices of adult and student tickets, respectively.
13a +12s = 211 . . . . . . ticket sales the first day
5a +3s = 65 . . . . . . . ticket sales the second day
Subtracting the first equation from 4 times the second gives ...
4(5a +3s) -(13a +12s) = 4(65) -(211)
7a = 49 . . . . . . . simplify
a = 7 . . . . . . . divide by 7
5(7) +3s = 65 . . . . substitute into the second equation
3s = 30 . . . . . . . subtract 35
s = 10 . . . . . . . divide by 3
The price of one adult ticket is $7; the price of one student ticket is $10.
Answer:
C. 5/7
Step-by-step explanation:
I'm pretty sure it's D because you're subtracting 30 without changing it.
The answer would be (-y, x).
Hope this helps.
