What is the additive inverse of the polynomial?<br> -7y^2+x^2y-3xy-7x^

gogolik [260]

The additive inverse of the polynomial $- 7{y^2} + {x^2}y - 3xy - 7{x^2}$ is $\boxed{7{y^2} - {x^2}y + 3xy + 7{x^2}{\text{ or }} - \left( { - 7{y^2} + {x^2}y - 3xy - 7{x^2}} \right)}.$

Further explanation:

Given:

The polynomial is $- 7{x^2} + {x^2}y - 3xy - 7{x^2}.$

Explanation:

The given polynomial is $- 7{y^2} + {x^2}y - 3xy - 7{x^2}.$

The additive inverse can be defined as when we add a number to some number and get result as zero.

The value of additive inverse is same as of the number but the sign of the additive inverse is opposite.

The additive inverse of the polynomial can be expressed as follows,

$\begin{aligned}A&= - 7{y^2} + {x^2}y - 3xy - 7{x^2} + \left( {7{y^2} - {x^2} + 3xy + 7{x^2}} \right)\\&= - 7{y^2} + 7{y^2} + {x^2}y - {x^2}y - 3xy + 3xy - 7{x^2} + 7{x^2}\\&= 0\\\end{aligned}$

The additive inverse of the polynomial $- 7{y^2} + {x^2}y - 3xy - 7{x^2}$ is $\boxed{7{y^2} - {x^2}y + 3xy + 7{x^2}{\text{ or }} - \left( { - 7{y^2} + {x^2}y - 3xy - 7{x^2}} \right)}.$

dem82 [27]

Answer:

The cost of goods sold per tie was $22

Step-by-step explanation:

The list of all associated cost in a month on the job 1041 is

Direct materials - $54,800
Direct Labour - $19,200
Selling $ Shipping Costs - $28,000
Overhead costs - $25 per MH × 320MHs = $8,000

The total cost of production of the ties can then be obtained by adding all associated costs;

$54,800 + $19,200 + $28,000 + $8,000 = $110,000

Total units of ties made from Job 1041 is 5,000

Therefore,

$Cost per unit tie = \frac{Total Cost of Production for all the Ties}{Total number of Produced Ties}$

$Cost per unit tie = \frac{110,000 dollars}{5000}$

Cost per unit tie = $22
