For the answer to the question above, it is -18% because to find rate we subtract the rate, in this case, is .82 or 82% - 1 or 100% and that would give you the rate, in this case, its decreasing by an 18%
I hope my answer helped you.
Part A
What is the 2010 federal income tax for a single person whose taxable income that year was 4000 dollars?
The function is
T(x)=0.1x
so
For x=4,000
substitute
T(x)=0.1*(4,000)
<h2>T(x)=$400</h2>
Part B
What is the 2010 federal income tax for a single person whose taxable income that year was 170000 dollars?
the function is
T(x)=0.28x-6,290.75
For x=170,000
substitute
T(x)=0.28*(170,000)-6,290.75
<h2>T(x)=$41,309.25</h2>
Part C
What is the taxable income for a single person whose 2010 federal income tax was 105000 dollars?
The function is
T(x)=0.28x-6,290.75
For T(x)=105,000
substitute
105,000=0.28x-6,290.75
solve for x
0.28x=105,000+6,290.75
0.28x=111,290.75
<h2>x=$397,466.96</h2><h2 />
This is what I got when i graphed it.
Answer:
m= -20/11
Step-by-step explanation:
Slope is equal to the change in <em>y</em> over the change in <em>x</em>, or rise over run.
m= change in y/ change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m

y
2

Substitute in the values of x and y into the equation to find the slope.
m= 3-(-17)/-6-(5)
m= -20/11
The answer is 7.68.
Hope this helps.
