2(4x+5)>7x+20 perform indicated multiplication on left side
8x+10>7x+20 subtract 7x from both sides
x+10>20 subtract 10 from both sides
x>10
or in interval notation, x=(10, +oo)
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:
B
• Compute the value of each expression.
• Compare the values. If they are equal, the expressions are equivalent.
Step-by-step explanation:
After you Simplify each expression and Substitute a number for each variable you have to compute it and after you do you have to compare and then you will see if they are equal.
This is my first time doing this so If it is wrong Im sorry.
