A building worth $829,000 is depreciated for tax purposes by its owner using the straight-line depreciation method.
Delvig [45]

The value of the building would be $699,400 in 4 years.

<h3>What will be the value of the building?</h3>

Depreciation is the when the value of an asset reduces as a result of wear and tear. Straight line depreciation is a method used in depreciating the value of an asset linearly with the passage of time.

The equation that can be used to determine the value of the building with a straight line depreciation is:

Value of the asset = initial value of the asset - (number of months x deprecation rate)

y = 829,000 - 2700x

The first step is to determine the number of months it would take for the building to have a value of $699,400.

$699,400 =  829,000 - 2700x

829,000 - 699,400 = 2,700x

129,600 = 2,700x

x = 129,600 / 2,700

x = 48 months

Now convert, months to years

1 year = 12 months

48 / 12 = 4 years

Find the equation of the line that passes through the points (-3,0) and (4,2). Using point slope formula
astra-53 [7]

Answer:

\large\boxed{y-0=\dfrac{2}{7}(x+3)}\\\downarrow\\\boxed{y=\dfrac{2}{7}x+\dfrac{6}{7}}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

<em>m</em><em> - slopei</em>

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

======================================

We have the points (-3, 0) and (4, 2).

Substitute:

m=\dfrac{2-0}{4-(-3)}=\dfrac{2}{7}

Put the value of the slope and the coordinates of the point (-3, 0) to the equation:

y-0=\dfrac{2}{7}(x-(-3))

y-0=\dfrac{2}{7}(x+3)

Converto to the slope-intercept form (<em>y = mx + b</em>):

y=\dfrac{2}{7}x+\dfrac{6}{7}

Triangle abc has the angle mesausres shown. Which statement is true about the angles?
Umnica [9.8K]

Answer:

m∠A = 20°

Step-by-step explanation:

Given that the sum of the angles of any triangle is 180°, adding the expressions of each angle and setting them equal to 180° will give the value of 'x' and allow you to evaluate the angles.  

2x + 5x + 11x = 180

18x = 180

18x/18 = 180/18 or x = 10

m∠A = 2x or 2(10) = 20°

m∠B = 5x or 5(10) = 50°

m∠C = 11x or 11(10) = 110°

Out of the choices given, the only one that is true is that m∠A = 20°.
