Answer:
$1.25 & $10.25
Step-by-step explanation:
Let c be the cost of renting one chair and t be the cost of renting table. We're given two equations:
#1. 5c + 3t = 37
#2. 2c + 6t =64
We have a system of equations. Using our system of equations calculator, we can solve this problem any of 3 ways below:
- Chairs (c) cost $1.25
- Tables (t) cost $10.25

Step-by-step explanation:
Given the equation: 
 y = 0.09x where: 
- x: represents the cost of the item before tax is added.
- y: represents the amount of sales
=> On a coordinate plane, the x-axis is labeled Cost of Item (in dollars) and the y-axis is labeled sales tax (in dollars)
We create a table of values
x    y 
0   0
10  0.9
=> the line go through two points (0, 0) and (10, 0.9) 
Hence tow dwaw a graph, we just connect two points together.

Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

Here is some answers
1. 2x+3y=1,470
 -2x -2x
---------------------
3y=-2x+1,470
---- --------
3 3
------------------
y=-2x+490
2. rise
 -----
 run
y=-2
 ---
 1
Find 490 and either go up 2 down 1 or down 2 up 1 either way you will get a straight line.
3. f(x)=2x+490
Don-t know how to explain this :(
I'm confused after this question
 Hope this helped a little
