<h3>Answer:  D)   y+3</h3>

==========================================================

Explanation:

Point A is located at (3,1). Point A' is located at (-5,4)

To move from A to A', we'll do two things:

  • Move 8 units to the left
  • Move 3 units up

The "8 units to the left" portion has us go from x to x-8

The "3 units up" part involves y becoming y+3

So that's how we get the translation rule (x,y) \to (x-8,y+3). The x-8 portion is already filled in for us. The missing part is y+3 which is the final answer (choice D).

Let's try this translation rule on point B to see if we arrive at the proper location of B'

B is at (2,6) which means

(x,y) \to (x-8,y+3)\\\\(2,6) \to (2-8,6+3)\\\\(2,6) \to (-6,9)\\\\

which matches up what the diagram shows. I'll let you verify that the rule also works for point C.

Remember that the y-intercept is where the function has a value of x = 0 and the x-intercept is where the function has a value of y = 0. Thus, to find the x-intercept and y-intercept, we can substitute these values into the equation and solve for the other variable.


<u>x-intercept</u>

Since the x-intecept has a y-value of 0, we can substitute this into the function and solve for x.

0 = -2x - 3

  • Set up

3 = -2x

  • Add 3 to both sides

x = - \dfrac{3}{2}

  • Divide both sides by -2

The x-value of the x-intercept is -\frac{3}{2} and the y-value is 0, meaning that the x-intercept has coordinates \boxed{(-\frac{3}{2}, 0)}.


<u>y-intercept</u>

Since the y-intercept has a x-value of 0, we can substitute this into the equation and solve for y:

y = -2(0) - 3

  • Set up

y = -3

  • Multiply and simplify

The y-value of the y-intercept is -3, meaning that the y-intercept of the function is \boxed{(0, -3)}.

Factor the GCF: 9x4y − 6x3y2 3x2y3. 3x2y(3x2 − 2xy y2) 3xy(3x2 − 2xy y2) 3xy2(3x2 − 2xy y2) 3x2y(3x2 2xy y2).
Papessa [141]

The factored form of the equation 9x⁴y - 6x³y² + 3x²y³ is 3x²y(3x²-2xy+y²).

<h3>What is factored form?</h3>

The product of a constant and two linear expressions in factored form. The roots of the function are the parameters and the x-intercepts of the graph. Often Factoring is referred to as the process of converting a quadratic function to factored form.

We need to write the given expression 9x^4y-6x^3y^2 + 3x^2y^3 in the factored form, therefore, we will take the common terms out of the given expression,

1. Taking 3 as the common term, we will get,

9x^4y-6x^3y^2 + 3x^2y^3\\\\= 3 (3x^4y-2x^3y^2 + x^2y^3)

2. Taking x² as the common term

= 3 (3x^4y-2x^3y^2 + x^2y^3)\\\\= 3x^2(3x^2y-2xy^2+y^3)\\\\

3. Taking y as the common term,

= 3x^2(3x^2y-2xy^2+y^3)\\\\= 3x^2y(3x^2-2xy+y^2)\\\\

Hence, the factored form of the equation 9x⁴y - 6x³y² + 3x²y³ is 3x²y(3x²-2xy+y²).
