A company has determined that its weekly profit is a function of the number of items that it sells. Which equation could represe
Mrac [35]

Answer:

B. y= -x^2+50x-300

Step-by-step explanation:

A. y^2=4x^2-100

B. y= -x^2+50x-300

C. x=-y^2-400

D. x^2=-6y^2+200

we are to find profits (y) when the company sells x items

Option A can be used to calculate the profit (y) squared

Option B can be used to calculate profits (y)

Option C can be used to calculate items sold(x)

Option D can be used to calculate items sold squared(x^2)

We are asked to find the weekly profit (y) function which eliminate options A, C and D leaving us with option B

Therefore, the weekly profits (y) function in thousands of dollars when the company sells x items is

B. y= -x^2+50x-300

Y varies inversely with x. When x = 3 then y = 5. Write a function to represent this relationship.
Mariulka [41]

Answer:

<em>The function to represent this relationship will be:  y= \frac{15}{x}</em>

Step-by-step explanation:

y  varies inversely with  x. That means......

y= \frac{k}{x}..............................(1)  

where k is a proportional constant.

Given that, when x=3, then y=5

Plugging these values into the above equation, we will get.....

5=\frac{k}{3}\\ \\ 5(3)=\frac{k}{3}(3)\\ \\ 15=k

Now plugging this k=15 into equation (1).....

y= \frac{15}{x}

So, the function to represent this relationship will be:  y= \frac{15}{x}
