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|
Your y-intercept would be (0,-13)
Answer:
136
Step-by-step explanation
multiply 4 by 31 and add 20
The solution for the system of equations are:
Attached is the graph of lines y=3x-2 and y=-2x+5.
5 and 1/4 times 3. 1/4 is equal to .25. So, 5.25 x 3 is...
15.75
