x= -15/4 => x= -3 3/4 or x= -3.75
Answer:
4 + 3x
Step-by-step explanation:
2 + 2 = 4
Add the three x's together and you get 3x!
Hope this helps! ^^
Make a change of coordinates:
The Jacobian for this transformation is
and has a determinant of
Note that we need to use the Jacobian in the other direction; that is, we've computed
but we need the Jacobian determinant for the reverse transformation (from
to
. To do this, notice that
we need to take the reciprocal of the Jacobian above.
The integral then changes to
Y = |x - 21| represents an absolute value function.
