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.
Please have a look at the attached photo.
Answer:
<h2>y = -4x</h2>
Step-by-step explanation:
Solve 20x + 5y = for y
20x + 5y = 0
subtract 20x both sides
5y = -20x
simplify:
y = <u>-20x</u>
5
finally
y = -4x
Answer:
Step-by-step explanation:
commutative property of addition : x + y = y + x
example : 2+3 =5 and 3+2 =5 then 2+3=3+2
associative property of addition
x + y + z = (x + y) + z = x + (y + z)
example: 2+3+4 = (2+3)+4 = 5 + 4 =9
2+3+4 = 2+(3+4) = 2 + 7 = 9
