Points e's x-and y-coordinates have different signs (one is positive and the other is negative). neither coordinate is 0. where could point e be located on the coordinate plane?

II and IV quadrant

Step-by-step explanation:

Given a point E  such that it's x-and y-coordinates have different signs (one is positive and the other is negative). Also, neither coordinate is 0 .

Coordinate Plane :

In quadrant I:

x-coordinate is +

y-coordinate is +

In quadrant II:

x-coordinate is -

y-coordinate is +

In quadrant III:

x-coordinate is -

y-coordinate is -

In quadrant IV:

x-coordinate is +

y-coordinate is -

Therefore, as  point E's x-and y-coordinates have different signs (one is positive and the other is negative), so E point may lie in second or fourth quadrant .

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
