Answer:
This is a reflection about the x-axis.
Step-by-step explanation:
A reflection about the x-axis has the rule
[x,y]-> [x,-y].
Therefore
M[x,y] = [x,-y}
Let M=
|a b|
|c d|
Then the matrix multiplication gives
ax+by=x.............(1)
cx+dy=-y............(2)
Solving the previous equations (1) and (2) gives
a=1, b=0
c=0, d=-1
giving M as
|1 0|
|0 -1|

Answer:
D) J
B) point Q
Step-by-step explanation:
we know that the ginipigs are only given 80 in total. that means 80 is 100%
40÷80*100=50%
20÷80*100=25%
10÷80*100= 12.5%
10÷80*100= 12.5%
all this together is 100%
meaning the best answer is
Q is the only place that = -1/2
