The reflection line is located at y = -x

For point J, x is -2, so y = -(-2), which equals 2.

When it is a reflection across Y, the X values remain the same.

Find the distance of the Y point to the reflection line,

The distance from -1 to 2 is 3 units.

The new point needs to be the same distance from the reflection line.

2 + 3 units = 5.

Point J' would be (-2,5)

When deriving the quadratic formula by completing the square, what expression can be added to both sides of the equation to crea

____ [38]

Answer:

According to steps 2 and 4. The second-order polynomial must be added by $-c$ and $b^{2}$ to create a perfect square trinomial.

Step-by-step explanation:

Let consider a second-order polynomial of the form $a\cdot x^{2} + b\cdot x + c = 0$ , $\forall \,x \in\mathbb{R}$ . The procedure is presented below:

1) $a\cdot x^{2} + b\cdot x + c = 0$ (Given)

2) $a\cdot x^{2} + b \cdot x = -c$ (Compatibility with addition/Existence of additive inverse/Modulative property)

3) $4\cdot a^{2}\cdot x^{2} + 4\cdot a \cdot b \cdot x = -4\cdot a \cdot c$ (Compatibility with multiplication)

4) $4\cdot a^{2}\cdot x^{2} + 4\cdot a \cdot b \cdot x + b^{2} = b^{2}-4\cdot a \cdot c$ (Compatibility with addition/Existence of additive inverse/Modulative property)

5) $(2\cdot a \cdot x + b)^{2} = b^{2}-4\cdot a \cdot c$ (Perfect square trinomial)

According to steps 2 and 4. The second-order polynomial must be added by $-c$ and $b^{2}$ to create a perfect square trinomial.

The financial statements of the Tyler Company report net sales of $300,000 and accounts receivable of $50,000 and $10,000 at the

iragen [17]

Answer:

the accounts receivable turnover for the Tyler Company is 10

Step-by-step explanation:

The company report :

net sales = $300,000

account receivable = $50,000 and $10,000

to find the accounts receivable turnover, use the following formula:

accounts receivable turnover = net sales : average account receivable

First, we need to calculate the average account receivable of the company

average accounts receivable = ($50,000+$10,000) : 2

= $60,000 : 2

= $30,000

Then, substitute net sales into the formula

accounts receivable turnover = $300,000 : $30,000

= 10
