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: A. $35.10
Step-by-step explanation:
Since the total money paid for the water for 3months is $95 and there are 31 days in October, 30days in November and 31 days in December totalling 92days. Therefore $95 was charged for water for 92days.
Since the owner sold the house and the rentage stopped 27th November, this shows the person only used water for (31+27) days i.e 58 days in the house.
The amount that will be received by the owner upon closing will be;
Since 92days of water used is equivalent to $95
58days will be equivalent to 58×95/92 = $59.9
The amount received will be
95-59.9 = $35.10 (A)
