Answer:
25, 9
Step-by-step explanation:
(p . q)(8) means do q first to 8 then do p to that, which is the same as writing p(q(8)). Then just plug the numbers in.
q(8)=√8+8=√16=4
p(4)=4^2+9=16+9=25
The second one is the opposite order but same reasoning.
p(8)=8^2+9=64+9=73
q(73)=√73+8=√81=9
The original price was $64
Hope this helps:)
-5x + y = -5.....multiply by -2
-4x + 2y = 2
---------------
10x - 2y = 10 (result of multiplying by -2)
-4x + 2y = 2
-----------------add
6x = 12
x = 12/6
x = 2
-5x + y = -5
-5(2) + y = -5
-10 + y = -5
y = -5 + 10
y = 5
solution is (2,5)
