Take the coefficients of each term and list them.

- 1 5 - 9

Multiply 3 by the first coefficient and combine it from the second. 

- 1 * 3 = - 3, 5 - 3 = 2

Multiply 3 by this product and combine it from the third term.

3 * 2 = 6, - 9 + 6 = - 3

Your remainder is option B, - 3.

Rosetta listed her assets and liabilities on a personal balance sheet.
avanturin [10]

Answer:

$50,000

Step-by-step explanation:

The computation of the amount received after paying off the mortgage is shown below

= Value of the house - mortgage amount

= $150,000 - $100,000

= $50,000

By deducting the mortgage amount from the value of the house we can get the amount received and the same is shown in the computation part

Since in the question it is given that the Rosetta sells her house and paid off mortgage so only these two items are considered and others are to be ignored

Solve the inequality W > Y plus H all divided by P for H.
maksim [4K]
Here is the answer to the given question above. So based on the given equality, W > y+h / P
So in order to solve this, let us eliminate the denominator by multiplying both sides by P so we get Wp > y + H. So to get the value of H, we are going to transfer y and it would look like this. Wp - y > H. So this is the final answer. Hope this helps.
