Answer:

-8y^{25}\\-9y^6\\5y^5

Step-by-step explanation:

First one.

((-y)^5)(8y^{20})=-y^5*8y^{20}=-8y^{5+20}=-8y^{25}

Second one

((-y)^{5} )(9y)=-y^5*9y=-9y^{5+1}=-9y^6

and last one

((-y)^5)(-5)=-y^5*(-5)=5y^5

The translation that maps triangle ABC to A prime B prime C prime would be a reflection across the y axis. This is because when you reflect something, you are pretty much flipping it. When you reflect across the y axis, you are flipping the triangle across the y axis. Take one point for example. I will use C. Notice how the point C is 3 units away from the y axis. So the same way you would move the point 3 units right from the y axis, and that would be your new point. This sounds kind of complicated, so I will give you a list of rules to make it more simple.


Reflection across y axis: (x,y) would be equal to (-x, y)
Reflection across x axis: (x,y) would be equal to (x, -y)
Reflection across y = x: (x,y) would be equal to (y,x)
Reflection across y = x: (x,y) would be equal to (-y,-x).

A reflection across y = x would be when you have a line that for every 1 it rises, it goes right 1. It is a positive line, as opposed to the y = -x line. It also has a slope of 1. I will try attaching a graph if I can.

Anyway, as I was saying. So pretty much if you don't want to go through the logic, to see whether a figure is reflected, just try each of these rules and if one works then you have your answer. Otherwise it would not be a reflection.

Thanks for being a great mod and hope this helps! :D

Find the multiplicative inverse of -2 in mod 7<br>​
Elis [28]

Answer:

  1. So something mod 7 is -2
  2. Lets consider what mod does as a commands: If you have 7 and then mod it by 2 ie 7%2 you get 1
  3. Essentially mod is seeing how many times a # goes into the other number and finding the remainder.
  4. In this case we want the remainder of 2: -8%3 =-2
  5. note there is also a mathematical procedural way to solve this.
