y is the horizontal line @ -1 below the x-axis. Graph the point, then flip it across. The x coordinate stays the same, the y changes.
Answer: (-2, -3)
The degree of the resulting polynomial, 5x^4^y² - x^3y - 12y + 8x, after subtraction is: degree 4.
<h3>How to Subtract Polynomials?</h3>
Given, (10x^4y^2 - 9x^3y - 9y) - (5x^4^y2 + 10x^3y + 12y - 8x), to subtract, open the parentheses using the distributive property.
10x^4y^2 - 9x^3y - 9y - 5x^4^y² - 10x^3y - 12y + 8x
Combine like terms together
10x^4y^2 - 5x^4^y² - 9x^3y - 10x^3y - 9y - 12y + 8x
5x^4^y² - x^3y - 12y + 8x
The highest degree is 4. This determines the degree of a polynomial.
Therefore, the degree of the resulting polynomial, 5x^4^y² - x^3y - 12y + 8x, after subtraction is: degree 4.

Answer:
(12 + n/3) = 2n + 1
Step-by-step explanation:
(12 + n/3) = 2n + 1
36 + n = 6n + 3
33 = 5n
n = 33/5
9z + 10 = 1 - 3(5 - 3z) use distributive property
9z + 10 = 1 + (-3)(5) + (-3)(-3z)
9z + 10 = 1 - 15 + 9z
9z + 10 = -14 + 9z subtract 9z from both sides
10 = -14 FALSE
NO SOLUTION
Answer: zero solutions.
