Determine whether each expression is a monomial or not 29, 5x/7
2s-9t
6m/2+7n
a/b2
2/3 xy/3z

monomial

not a monomial

not a monomial

monomial

monomial

Step-by-step explanation:

Hey There!

Monomials are expressions that consist of one term

So if the expression has a + or - sign then it is not a monomial

29, 5x/7 is considered a monomial

2s-9t is not a monomial because it has more than one term

6m/2+7n is not a monomial because it has more than one term

a/b2 is a monomial

2/3 xy/3z i believe this one is a monomial too

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'.
