Answer:
35 dollars
Step-by-step explanation:333-18=315 dollars
315/9=35 dollars for each book
X➝-x by reflection, so g(x)=-x
you have to read the bottom link for the answer key
Let z = sin(x).
.. z^2 -2z = 2
.. z^2 -2z +1 = 3
.. (z -1)² = 3
.. z -1 = ±√3
.. z = 1 -√3 . . . . . the positive solution is extraneous
sin(x) = 1 -√3
