Given =
Marcus earned $54,000 last year. social s ecurity tax was 6.2% and medicare tax was 1.45%
Find out he pay in Social Security and Medicare taxes last year.
To proof
Marcus earned last year = $ 54000
Social Security tax = 6.2%
Medicare tax = 1.45%
First find out the social security tax
6.2 % written in the simpler form =
= 0.062
Social Security tax last year = .062×54000
= $ 3348
find out Medicare taxes
1.45% Medicare tax written in the simpler form =
= 0.0145
Medicare taxes last year = 0.0145 × 54000
= $743
Total tax last year = $743 + $3348
= $ 4131
Hence proved

Answer:
1) The slope of the function is
and the slope of the function
is
.
2) The negative slope of the function shows that it is the line is increasing and the slope
of the function
shows that the line will always have the same y-coordinate.
3) The slope of the function is is greater than the slope of the function
.
Step-by-step explanation:
For this exercise you need to know that the slope of any horizontal line is zero ()
The slope of a line can be found with the following formula:
You can observe in the graph of the function given in the exercise, that this is an horizontal line. Then, you can conclude that its slope is:
The steps to find the slope of the function shown in the table attached, are the following:
- Choose two points, from the table:
and
- You can say that:
- Substitute values into the formula :
- Finally, evaluating, you get:
Therefore:
1) The slope of the function is
and the slope of the function
is
.
2) The negative slope of the function shows that it is the line is increasing and the slope
of the function
shows that the line will always have the same y-coordinate.
3) The slope of the function is is greater than the slope of the function
