Answer: you need a x and y axis to get this answer

Step-by-step explanation: first you put the (3,5) and (3,-7) in a graph paper then make an y and x axis and you will be able to see your answer visually

Answer:

No it is not possible.

Step-by-step explanation:

To find the slope of the coordinates, you plug in #s for (y2-y1)/(x2-x1)

(y2-y1)/(x2-x1)

-7-5=-12

3-3=0

-12/0 is not possible. Nothing is dividable by 0.

Easy Question pls help. (Algebra II type problems)
Roman55 [17]

Answer:

\large\boxed{if\ x\neq-3\ \wedge\ y\neq0\ \wedge\ x\neq y\ \wedge\ x\neq -y}

second

\large\boxed{y\neq0\ \wedge\ x\neq-y\ (y\neq-x)}

Step-by-step explanation:

We know that dividing by 0 is impossible.

Therefore, the denominator of the expression must be different from 0.

\text{For}\\\\\dfrac{(x-y)^2}{2xy+6y}\times\dfrac{4x+12}{x^2-y^2}\\\\\\2xy+6y\neq0\qquad(1)\\\\x^2-y^2\neq0\qquad(2)

(1)\\2xy+6y\neq0\qquad\text{distribute}\\\\2y(x+3)\neq0\iff2y\neq0\ \wedge\ x+3\neq0\\\\2y\neq0\qquad\text{divide both sides by 2}\\\boxed{y\neq0}\\\\x+3\neq0\qquad\text{subtract 3 from both sides}\\\boxed{x\neq-3}\\==========================\\(2)\\x^2-y^2\neq0\qquad\text{use}\ a^2-b^2=(a-b)(a+b)\\(x-y)(x+y)\neq0\iff x-y\neq0\ \wedge\ x+y\neq0\\\boxed{x\neq y}\ \wedge\ \boxed{x\neq-y}

\text{For}\\\\\dfrac{2(x-y)}{y(x+y)}\\\\y(x+y)\neq0\iff y\neq0 \wedge\ x+y\neq0\\\\ \boxed{y\neq0}\ \wedge\ \boxed{x\neq-y}

Add the following polynomial of x3+3xy-2×y2+y3,2×3-5x2y-3xy2-2y3<br>​
ANTONII [103]

The addition of the polynomial x^{3}+3xy-2xy^{2} +y^{3} with 2x^{3}-5x^{2} y-3xy^{2}-2y^{3} is  3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}.

What is a polynomial?

⇒ A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

⇒ In the addition of polynomials, the like terms are added while in subtraction, the like terms are subtracted.

Calculation;

We have been given two polynomial which we have to add   x^{3}+3xy-2xy^{2} +y^{3} and 2x^{3}-5x^{2} y-3xy^{2}-2y^{3}

The sign after addition or subtraction will always be of the variable having more value.

(x^{3}+3xy-2xy^{2} +y^{3} )+(2x^{3}-5x^{2} y-3xy^{2}-2y^{3})

On adding like terms with each other

⇒ (x^{3} +2x^{3})+ 3xy-5x^{2} y-(2xy^{2}+3xy^{2})+(y^{3}-2x^{3})

⇒ 3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}

Hence the addition of the polynomialx^{3}+3xy-2xy^{2} +y^{3} and 2x^{3}-5x^{2} y-3xy^{2}-2y^{3} is 3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}.
