Which number sentence is not true? OA) |-20| < 20
OB) |9| = 9
OC) |-20| > |9|
OD) |9|< 20

Option A is correct option

Step-by-step explanation:

We need to find which number sentence is not true.

We will check each option.

Option A

|-20| < 20

We know that |-a|=a

20 < 20 (false)

So, this number sentence is not true.

Option B

|9| = 9

We know that |a|=a

9=9 (true)

So, this number sentence is true.

Option C

|-20|>|9|

We know that |-a|=a

20>9 (true)

So, this number sentence is true.

Option D

|9| < 20

We know that |a|=a

9<20

So, this number sentence is true.

So, Option A is correct option

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'.

i saw this question before, dont know the asnwer srry
