5 0

Answer:

-200

Step-by-step explanation:

We are given that:

  • P= -5
  • Q= -15

Simply insert this values into their correspondents in the equation given.

(-5 + (-15)) * (-5 - (-15))

Subtracting two negatives is like adding a positive and a negative.

(-5 + (-15)) * (-5 + 15)

Solve inside the parenthesis.

(-20) * (10)

Multiply.

-200

Andreyy89

Answer:

/75

Step-by-step explanation:

As I couldn't take the radical symbol I used this - "/".

5 /3

If 5 has to come in the radical sign it has to be squared

So, /25 × /3

/25×3

/75

We factor the equation to get:

-(x-25)^2+361

In the form a(x-h)^2+k, the vertex is (h, k), so the vertex is (25, 361).  This means that the studio makes the most profit from selling 25 memberships, and thus makes 361 dollars.

B.  The x-intercepts are the values of x for which f(x) is 0.  This equation can be factored as (-a+6)(a-44)=0, with solutions 6 and 44.  Therefore, by selling either 6 memberships or 44 memberships, the studio breaks even, neither making nor losing money.

What is y=-10x's constant of proportionality and how would describe a graph's constant rate of change.
Fantom [35]
Okay, so here, we know that -10 is the slope, therefore, it is also the constant of proportionality. 

'x' is the unknown value, that tells us to multiply by -10. 

So, on a graph, we would consider that per unit, it would decrease by -10, since its a negative slope. 

Hope I helped, if you have further questions or concerns, feel free to PM me. Thanks! :D
