Determine positive and negative rational numbers

As a point of reference, we have the following

$\frac{+}{+} = +$ --- (1)

$\frac{-}{+} = -$ --- (2)

$\frac{+}{-} = -$ --- (3)

$\frac{-}{-} = +$ --- (4)

(a): $\frac{+2}{+3}$

See (1) above;

So, we have:

$\frac{+2}{+3} = +\frac{2}{3}$

Hence, this is positive

(b): $\frac{+2}{-3}$

See (3) above;

So, we have:

$\frac{+2}{-3} = -\frac{2}{3}$

Hence, this is negative

(c): $\frac{-1}{-3}$

See (4) above;

So, we have:

$\frac{-1}{-3} = +\frac{1}{3}$

Hence, this is positive

(d): $\frac{-1}{+3}$

See (2) above;

So, we have:

$\frac{-1}{+3} = - \frac{1}{3}$

Hence, this is negative.

(e): $\frac{+1}{-3}$

See (3) above;

So, we have:

$\frac{+1}{-3} = -\frac{1}{3}$

Hence, this is negative

(f): $\frac{-2}{-3}$

See (4) above;

So, we have:

$\frac{-2}{-3} = +\frac{2}{3}$

Hence, this is positive

(g): $\frac{+1}{+3}$

See (1) above;

So, we have:

$\frac{+1}{+3} = +\frac{!}{3}$

Hence, this is positive

(h): $\frac{-2}{+3}$

See (2) above;

So, we have:

$\frac{-2}{+3} = - \frac{2}{3}$

Hence, this is negative.

Answer from: Quest

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did not satisfy the given simplify expression.
