Answer:

Option C is correct .i.e., the unit price(s) when the profit is equal to 0.

Step-by-step explanation:

Given Expression: -0.5x² + 22x - 224

Given Expression gives monthly profit of the product for unit price of the product that is value of x.

Zero(s) of the expression means the value of variable for which the value of whole expression equals to zero.

So, Option C is correct as whole expression equal to zero means profit equal to zero and value of variable means unit price of product.

Therefore, Option C is correct .i.e., the unit price(s) when the profit is equal to 0.

Given that p=x^2-y^2/x^2+xy
Nataly [62]

Answer:

p = - \frac{1}{2}

Step-by-step explanation:

Given

p = \frac{x^2-y^2}{x^2+xy} ( factorise numerator and denominator )

x² - y² ← is a difference of squares and factors as (x - y)(x + y)

x² + xy ← factor out x from each term

= x(x + y) , thus

p = \frac{(x-y)(x+y)}{x(x+y)} ← cancel (x + y) on numerator/ denominator

   = \frac{x-y}{x} ← substitute x = - 4, y = - 6

   = \frac{-4-(-6)}{-4}

   = \frac{-4+6}{-4}

    = \frac{2}{-4} = - \frac{1}{2}
