Answer:
A) reflection across the y-axis
Step-by-step explanation:
If 
, then this says that two 
-coordinates are equal for opposite values of 
.
Let 
a point on 
.
Then 
.
We also know that 
and therefore 
is also a point on the graph.
If you graph [/tex](-a,b)[/tex] and you will see they are symmetrical to each about the -axis.
Example if given both and 
, then 
. This means both (2,3) and (-2,3) are points on the graph.
Here is what those two points look like on a Cartesian Plane (please see graph in picture).
I hope it helps you ❤️❤️❤️❤️

Answer:
- square: 12 ft sides
- octagon: 6 ft sides
Step-by-step explanation:
This problem can be worked in your head.
If the perimeters of the square and regular octagon are the same, the side length of the 4-sided square must be the same as the length of 2 sides of the 8-sided octagon. Since the side of the square is 6 ft more than the side of the octagon, each side of the octagon must be 6 ft, and each side of the square must be 12 ft.
__
We can let s represent the side length of the octagon. Then we have ...
8s = perimeter of octagon
4(s +6) = perimeter of square
These are equal, so ...
4(s +6) = 8s
s +6 = 2s . . . . . . divide by 4
6 = s . . . . . . . . . . subtract s
The octagon has 6-ft sides; the square has 12-ft sides.
Answer:
Step-by-step explanation:
* 33/100 = .3(bar)
* 23/50 =.46
* 6/8 = .75
* 1/3 = .3(bar)
* 7/10 =.7
* 21/81 = .26
* 3/16 = .1875
* 7/20 =.35
