Can someone explain to me why the answer to [write equation using polar coordinates] 3x^2+3y^2=6y is 3r^2- 6rsin(theta)=0 (textbook answer)? why not r-2sin(theta)=0? is one more preferred and why?

is valid.

is equally valid.

is not technically valid because it's possible that , and you can't divide through the above equation by 0. The plots of all three of these options are identical, however.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

your question is incomplete, write all the numbers in the sequence that it tells you.
