Well if they give us tan so that means the triangle is

b=15, a=8... So now we need C
So use the <span>pythagorean <span>theorem 
8^2 + 15^2 = c^2
c=17

So now sin is OPP/HYP so
sin (a) = 15/17 = .88</span></span>

Find all solutions for 2y - 4x =2 y = 2x + 1 site:socratic.org
sladkih [1.3K]

Answer:

All real numbers would be the solution

Step-by-step explanation:

2y - 4x =2 and y = 2x + 1

We solve but placing the value of y into the first equation:

2(2x + 1) - 4x = 2

Next we distribute the 2 through the parenthesis:

4x + 2 - 4x = 2

Now we gather like terms:

2 = 2 ( note the 4x and - 4x cancel out)

Since 2 =2 this tells us that all real numbers would work.

In August 2016, Richard purchased and placed in service an office building costing $753,000, including $134,000 for the land. Th
Schach [20]

Only the building is depreciable

so the depreciable portion is $753,000 less <span>$134,000  </span>land, for a net of $619,000

 The MACRS rules (Modified Accelerated Cost Recovery System ) provide a 39-year life, straight-line depreciation, and a "mid-month" acquisition convention that treats the property as acquired in the middle of the month, regardless of the actual date of acquisition.

 Therefore, the August 1, Year 2016, service date provides a half-month's depreciation for August, plus a full month for September through December, for a total of 4.5 months for Year 2016. $619,000 /39 years) × (4.5/12) = $5,952.
