For this case we have that by definition, the commutative property of multiplication states that the order of the factors does not alter the product. That is to say:

$a * b = b * a$

Example:

$4 * 5 = 5 * 4\\20 = 20$

Answer:

The commutative property of multiplication states that the order of the factors does not alter the product.

Answer:

$y = \frac{1}{8}(x + 4)^2 + 4$

Step-by-step explanation:

Given:

Focus of parabola: (-4, 6)

Directrix: y = 2

Required:

Equation for the parabola

<h2><u>SOLUTION:</u></h2>

Using the formula, $y = \frac{1}{2(b - k)}(x - a)^2 + \frac{1}{2}(b + k)$ , the equation for the parabola can be derived.

Where,

a = -4

b = 6

k = 2

Plug these values into the equation formula

$y = \frac{1}{2(6 - 2)}(x - (-4))^2 + \frac{1}{2}(6 + 2)$

$y = \frac{1}{2(4)}(x + 4)^2 + \frac{1}{2}(8)$

$y = \frac{1}{8}(x + 4)^2 + \frac{8}{2}$

$y = \frac{1}{8}(x + 4)^2 + 4$

If x-2y=0 and 3x + y =7 what is the value of x

Agata [3.3K]

Answer:

x=2

Step-by-step explanation:

If 3x + y = 7, then y= 7 - 3x.

Substitute in x - 2y = 0

So:

x - 2(7-3x)=0

x-14+6x=0

7x=14

x=2
