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.
Her investment was $4500. To get this, you take 1890 and divide it by 7, giving you 270. This is 6% of 4500. To prove this, you would multiply 4500 by .06, giving the answer of 270, which can then be multiplied by 7 (years) to equal $1890.
Step-by-step explanation:
5x + 80 = 180
x = 20
2x = 40
3x=60
7x=140
