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

A and B are correct because 96/100 is equivalent to 0.96, which is also 96%.
Answer :
y = 3x + 1
Explanation:
Answer:
a = 6
Step-by-step explanation:
–6(2 + a) = –48
-12 - 6a = -48
<u>+12 +12</u>
-6a = -36
a = -36 ÷ - 6
a = 6
