I think it's 5x - y= -6
Cuz when you put the 6 on the other side you do 0-6 which is -6

Step-by-step explanation:

1) First, before getting started, let's assume the price of the product is $x$ . This variable will be used a lot throughout the problem ( $x$ ).

2) Marking a price above means increasing the price in order to make money off of the purchased product. When raising something by $y$ percent, the new price would be $x + \frac{y}{100}*x$ .

---> In this case, the price increased by $\textbf{30}$ percent.

This means that it would be: $x+\frac{30}{100}x = x+0.3x=1.3x$

New price is: $1.3x$

3) The shopkeeper is then offering a $\textbf{15}$ percent discount off of this marked price. When offering a $b$ percent discount price, the new price (with discount), expressed algebraically is: $a-\frac{b}{100}a$

---> the expression above simplifies to $(1-\frac{b}{100})a$

In this case, $a=1.3x$ , $b=15$

---> $(1-\frac{15}{100})*1.3x = (1-0.15)*1.3x=0.85*1.3x=1.105x$

This means that $x$ , with discount, has been raised $\textbf{10.5 percent}$ .

10.5 % is the profit percent

(The profit percent being the final marked up price - purchased price)

If you’re using the inspection method, what constant term would you need in the numerator of this rational expression for (x+5)

Eva8 [605]

If I am using the inspection method, the constant term that I would need in the numerator of this rational expression for (x+5) to be a common factor of (x^2+6x+14) / (x+5) is 11/(x+1)

Answer:

$- 11a(3a + 2b) \\ = - 11 \times 3 \times a \times a + ( - 11 \times 2 \times a \times a) \\ = - 33 {a}^{2} - 22ab$
