The Jacobian for this transformation is

with determinant
, hence the area element becomes

Then the integral becomes

where
is the unit circle,

so that

Now you could evaluate the integral as-is, but it's really much easier to do if we convert to polar coordinates.

Then

Answer:
x= - AB-4/5 and No Solution
False for all xER
Step-by-step explanation:
Answer:
(12x - 6)/5
Step-by-step explanation:
6(2x-1)/5 => (12x - 6)/5 because of the distributive property.
You cannot simplify farther after you reach (12x - 6)/5.
A point doesn't have slope. Once you have TWO points, then the line between them has a slope.
The slope is (how far the line rises from one point to the other) divided by (the level distance between them).
