-4 + x    2 + y
------- = 5 and   ------ = 5
2       2

so x = 10 + 4 = 14 and y = 10 - 2 = 8

endpoint N = (14,8)

The total cost of a color printer is $186.16 including tax. If the tax rate is 7%, what is the original cost of the color printe

Galina-37 [17]

Answer:

The original cost of the printer before adding the tax was $ 173.98

Step-by-step explanation:

Total cost of the color printer, including tax = $ 186.16

Tax rate = 7%

Original cost of the printer, before tax = x

For answering the question, let's use the Rule of Three Simple, this way:

Percentage Value

107% 186.16

100% x

x * 107 = 186.16 * 100

107x = 18,616

x = 18,616/107

x = 173.98

The original cost of the printer before adding the tax was $ 173.98

Find the 75th term of the arithmetic sequence 16, 15, 14,

slega [8]

Answer:

$a_{75}=-58$

Step-by-step explanation:

This is an arithmetic sequence:

$a_n=a_1+(n-1)d$

where d is the common difference and n is the index of any given term.

For the given sequence, the common difference is -1:

$15-16=-1\\14-15=-1$

Knowing both the common difference and the first term, you can write the equation for this sequence:

$a_n=16+(n-1)(-1)$

Then you can use that equation to find the 75th term:

$a_{75}=16+(75-1)(-1)\\a_{75}=16+(74)(-1)\\a_{75}=16-74\\a_{75}=-58$
