Hi there!
Reflections across the line y = -x always go by the rule (-y, -x). We can use this rule to get our answer here. We are given the aftermath of the reflection coordinates, which are <span>A'(-1, 1), B'(-2, -1), and C'(-1, 0). All we have to do now is switch up the coordinate values and multiply them by -1. Here is the work -
A'(-1, 1) => (1, -1) => x -1 => A(-1, 1)
B'(-2, -1) => (-1, -2) => x -1 => B(1, 2)
C'(-1, 0) => (0, -1) => x -1 => C(0, 1)
Therefore, the coordinates of Triangle ABC are A(-1, 1); B(1, 2); C(0,1). Hope this helped and have a phenomenal day!</span>

Answer:
Karen has only 2 checkers left
Step-by-step explanation:
Jasper has 7 checkers than Karen
Jasper has 9 checkers
The equation can be written as
7 + k = 9
This means that 7 plus Karen checkers equal 9 which is jasper checkers
It can also be written as
9 - 7 = k
k = 2
Therefore Karen has only 2 checkers left
Answer:
I cant really see its up side down if you can do it again the right way then I tell you what it is but its kinda hard to see the way im seeing it
7.
assuming you mean SURFACE area
look at shape
fold it out or whateveryo yo like
we see that the faces are
4 triangles
4 rectangles in midddle
4 more triangles on other side
calculate areas
area of triangle=1/2bh
area of rectangle=bh
leftmost side
h=1.8
b=2
4*1/2*2*1.8=7.2 cm^2
middle recangles
base=3
height=2
aera=3*2=6
multply by 4 snce 4 recangles
6*4=24 cm^2
other triangles
b=2
h=2.71
total area=4*1/2*2*2.71=10.84cm^2
add them up
7.2cm^2+24cm^2+10.84cm^2=42.04cm^2
8. interesting question, not enought time to answer for me and partially too copmplex
