All of them can be accomplished with electronic banking, but C and D would be easiest to do online.
Answer:
yes
Step-by-step explanation:
d f xcdg
Old coordinate
As center of dilation is origin the scale factor only multiplied with B
So
new coordinate
B'
- 1/2(2,-6)
- (2/2,-6/2)
- (1,-3)
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|
A) The estimated total expense is
.. $600 +300 +200 +100 +200 = $1400
b) The estimated remaining to be saved is
.. $1400 -800 = $600
