Which expression is equivalent to the product of p+7/3 and 6/p , where p is not equal to 0?

vichka [17]

Answer:

$\frac{(6p+14)}{p}$

Step-by-step explanation:

$(p+\frac{7}{3})(\frac{6}{p})$

Making denominator same in first bracket we get

$(\frac{3p+7}{3})(\frac{6}{p})$

$(\frac{(3p+7)*6}{3*p})$

Dividing 6 by 3 we get 2

$(\frac{(3p+7)*2}{p})$

using distributive law

$(\frac{6p+14}{p})\\$

Hence this is our answer

A tractor was purchased for $30,000 six years ago. what is the value of the tractor today if the depreciation rate was 2.5%?

MrRissso [65]

Initial cost = $30,000
Depreciation rate = 2.5%

Depreciation expense per year = 30,000*2.5/100 = $750
In six years,
Depreciation = 6*750 = $4,500

Value of the tractor = Initial cost - Depreciation = $30,000 - $4,500 = $25,500

What's is an equation of the line that passes through the point(-3,-1) and is perpendicular to the line x-2y=6

katrin2010 [14]

Answer:

$y+1=-2(x+3)$

Step-by-step explanation:

Slope is negative reciprocal when two lines are perpendicular

m1=1/2 therefore m2=-2

The equation of the line in point-slope form is given as

$y-y_1=m_2(x-x_1)$

Here m=-2 and (x1, y1)=(-3, -1)

Therefore,

$y+1=-2(x+3)$
