Can you explain the question in words please?
G(5) = 2(5)-5=5
h(2)=4(2)+5=13
So, g(5)+h(2)=13+5=18.
10% of 46.80 =4.68
46.80 + 4.68 = 51.48
Hope this helps :D
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|
