(17 points and brainliest!) If the point (x, y) is in Quadrant IV, which of the following must be true? A. x > 0 and y 0 C. x > 0 and y > 0 D. x < 0 and y < 0

Quadrants are simply the axes of a 2D coordinate that divides a plane into four segments.

The true statement is that: (a) x > 0 and y < 0

First, we analyze each quadrant

Quadrant 1

Quadrant 2

Quadrant 3

Quadrant 4

By comparing the above to the list of given options,

The true statement about quadrant IV is (a) x > 0 and y < 0

x>0 and y<0

Step-by-step explanation:

Quadrant IV is the bottom right corner.

X would have to be positive and Y would have to be negative.

step-by-step explanation: where's the phrase?

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
