It is known that the point P(-9,18) belongs to the graph of the function y=k/x. Find k.
riadik2000 [5.3K]

Answer:

k = (-162).

Step-by-step explanation:

A point of the form (x_{0},\, y_{0}) belongs to the graph of this function, y = k / x, if and only if the equation of this function holds after substituting in x = x_{0} and y = y_{0}.

The question states that the point (-9,\, 18) belongs to the graph of this function. Thus, the equation of this function, y = k / x, should hold after substituting in x = (-9) and y = 18:

y = k / x.

18 = k / (-9).

Solve this equation for the constant k:

\begin{aligned}k &= 18 \times (-9) \\ &= (-162)\end{aligned}.

Thus, k = (-162).

1 ) $45, the markup is 20%. <br> 2) 1.25 the markup is 80%<br> 3) 150. the markdown is 40%
baherus [9]
Hi there! I can help you with these! For these types of questions, all you have to do is that if there is a markup, multiply by one hundred something to get the new price, because you're including the original price and the markup. For example, if there is a 75% markup on something, you multiply by 175% (1.75). Or, if there is a markdown, basically multiply by the remaining percentage. For example, if the markdown is 35%, you multiply the original price by 65% (0.65), because that is the amount of the price that it's on sale for. With that being said, if you do this correctly, here are the answers:

1. $54
2. $2.25
3. $90

Hopefully if you're talking about the markup or markdown from these prices, those are your answers.
