Tina Cole is a certified financial adviser. She purchased equipment for her office for $8,843. The trade-in value of the equipment is estimated to be $450 after 7 years of use. Using the straight-line method, what is the annual depreciation to the nearest cent?

Answers

Straight - line method allows the determination of the annual depreciation by dividing the total reduction in property value by the number of years. In the given above, The total depreciation of the value is $8,393. Dividing this value by 7 years gives $1,199/year. 

Therefore, the annual depreciation is $1,199.0

Answer:

$1,199 per year.

Step-by-step explanation:

Tina Cole is a certified financial adviser.

She purchased equipment for her office costs = $8,843

After 7 years of use the trade-in value of the equipment is estimated = $450

Total depreciation in 7 years = 8,843 - 450 = $8,393

We have to calculate the annual depreciation using the straight-line method.

So we divide $8,393 by 7

$8,393 ÷ 7 = $1,199

The annual depreciation of the equipment is $1,199 per year.

Answers

(2u² - 7) ÷ (u + 3)

2u² + 0u - 7 ÷ u + 3
                    2u - 6
u + 3 I 2u² + 0u - 7
         - 2u² + 6u
             0  -  6u - 7

Answer is: B. 2u - 6 R 11

What set of reflections would carry triangle ABC onto itself?

Answers

The correct answer is y-axis, x-axis, y-axis, x-axis. The y-axis is the vertical line, and the x-axis is the horizontal line. If the triangle is in the upper right quadrant, and is reflected first over the y-axis, it will be in the upper left quadrant. Then, when the triangle is reflected again over the x-axis, it will be in the lower left quadrant, diagonal to the initial triangle. When the triangle is again reflected over the y-axis, it will be in the lower right quadrant, below the initial triangle. Finally, when the triangle is reflected over the x-axis, it will be on top of the original triangle in the upper right quadrant.
