3. 28/ч - 2x3 =
Answer

28/4 - 2x^3 = 7- 2x^3

Hope this helps!

Step-by-step explanation:

This is the answer because:

You can use PEMDAS or GEMS to help you remember the order of operations.

PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

GEMS: Grouping (Parenthesis), Exponents, Multiplication and Division (whichever comes first from left to right), Addition and Subtraction (whichever comes first from left to right).

1) We have to use the order of operations in order to solve this.

2) First, we have to divide because it's the first thing there is, 28/4 = 7

3) Next, we have to multiply since we cannot subtract before multiplying because you have to follow the rules of Order of Operations. 2 x 3 = 6

4) Finally, 7 - 6 = 1

Hope this helps!

it would be 6xy and -16xy.

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'.
