The Council shall be the judge of the election and qualifications of its members. A majority of all the members elected shall be a quorum to do business, but a less number may adjourn from day to day, and compel the attendance of absent members in such manner and under such penalties as may be prescribed by ordinance. The affirmative vote of a majority of the members elected to the Council shall be necessary to adopt any ordinance or resolution. The vote upon the passage of all ordinances, and upon the adoption of such resolutions as the Council by its rules shall prescribe, shall be taken by "yeas" and "nays" and entered upon the journal.
