Which statements are true about all points on the x-axis? check all that apply. they have a y-value of 0. they have an x-value that is not 0. they are not to the left or to the right of the origin. they are in quadrant i. they are not in any of the quadrants. they are not above or below the origin.

They have a y-value of 0.                                           True
They have an x-value that is not 0.                             False
They are not to the left or to the right of the origin.     False
They are in Quadrant I.                                               False
They are not in any of the quadrants.                         True
They are not above or below the origin.                     True

The statement which are true about all the points on the x-axis are:

They have a y-value of 0.They are not in any of the quadrants. They are not above or below the origin.Step-by-step explanation:

The points in the x-axis are represent by the expression:

                (x,0) where x may belong to any real number.

This means that the y-value of such a point is definitely 0.Also, such a point will never lie below or above the origin.They may lie on the origin this means that the x-value need not be non-zero.Also, the points which are on the axis do not lie in any quadrant.They may lie to the left or to the right of the origin or on the origin itself.

A) for the n row: 22+(n-1)×6therefore,b) 100-22=78that means (n-1)×6=7878÷6=1313+1=1414th row has 100 seats
