5 + 8s = 15 + 3s
8s - 3s = 15 - 5
5s = 10
s = 10/5
s = 2 <=== they will charge the same at 2 sq ft
First of all get a picture of what this looks like. Desmos is a pretty good graphing program, but anything that will do polar coordinates will work.
Here is the graph.
What you can see is that this graph is symmetrical around the x axis.
When you talk about symmetry, you can think of it as taking a mirror and putting it where you think there is symmetry. If you can't tell the difference between the image and the real thing, then you have symmetry.
In this case, the mirror will show symmetry along the x axis and no where else.
Answer:

Step-by-step explanation:
Given

Determine LN
Since LM is a bisector, then we have:
(See attachment for illustration)

Collect Like Terms


Solve for w


LN is calculated as thus:

Substitute 4 for w



I’m sorry I don’t see a diagram for this. Could you please scan one?
Answer:
All Real Numbers
Step-by-step explanation:
Assuming that V is just a constant, you can re-write the equation as:
y = Vx-6.
This is a linear equation. Linear equations have a domain and range that both are "all real numbers".
