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

Answers

Answer 1

Answer:

Answer:

Additive inverse is (7y² - x²y + 3xy + 7x²).

Step-by-step explanation:

Let the additive inverse of the given polynomial be Y.

Therefore as per definition of additive inverse of any polynomial the addition of a polynomial and additive inverse of any polynomial is always zero.

So Polynomial + additive inverse polynomial = 0

(-7y² + x²y - 3xy - 7x²) + Y = 0

Y = -(-7y² + x²y - 3xy - 7x²) = (7y² - x²y + 3xy + 7x²)

So the additive inverse of the polynomial will be (7y² - x²y + 3xy + 7x²).

Answer 2

Answer:

Answer:

The answer is A

Step-by-step explanation:

The additive inverse is basically the opposite symbol for the numbers.

So, therefore:

What is the additive inverse of the polynomial?

-7y^2 + x^2y - 3xy - 7x^2

The answer to this would be

7y^2 - x^2y + 3xy + 7x^2

How much greater is 1 1/2 than 1/4

Answers

To find this you can subtract it by taking the improper fraction 1 1/2 and turning into a mixed number which will be 3/2. This make a it easier to subtract. You subtract 3/2 and 1/4 which you will get 5/4 which is also 1 1/4. So 1 1/2 is 1 1/4 greater than 1/4.

332(1000)= 3320

so the falcon can fly 3320 meters per hour

Equation for 14+ W= 26

Answers

Answer: w = 12

Step-by-step explanation: In this problem, we want to get w by itself on one side of the equation. Since we have 14 + W, in order to get w by itself, we must subtract 14 from the left side of the equation.

If we subtract 14 from the left side of the equation, we must also subtract 14 from the right side of the equation. So on the left, +14 and -14 cancel each other and on the right, 26 - 14 simplifies to 12 so w = 12.

To check our answer, we substitute a 12 back in for w in the original equation and we have 14 + (12) = 26 or 26 = 26 which is a true statement so the answer checks.
