There are no solutions to 2x-5y=9 but if you are solving it by y=mx+b form than your answer would look like this: y=2/5x-9/5
Answer:
27 I think just divide 81 by 3
Consider a circle with radius
centered at some point
on the
-axis. This circle has equation

Revolve the region bounded by this circle across the
-axis to get a torus. Using the shell method, the volume of the resulting torus is

where
.
So the volume is

Substitute

and the integral becomes

Notice that
is an odd function, so the integral over
is 0. This leaves us with

Write

so the volume is

Answer:
=−8x+−8
Step-by-step explanation:
Let's simplify step-by-step.
2−5x−10−3x
=2+−5x+−10+−3x
Combine Like Terms:
=2+−5x+−10+−3x
=(−5x+−3x)+(2+−10)
=−8x+−8
