Answer:

-2

Step-by-step explanation:

Start with the vertex form of the equation of a parabola:  y - k = a(x - h)^2

Here h = -2, k = -3, x = -1, y = -5.  Find a:

-5 - [-3] = a(-1 - [-2])^2, or

-5 + 3 = a(1)^2, or

-2 = a

The unknown coefficient is -2.

The president, vice-president, and financial officer of a company divide the profits is a 4:3:2 ratio. If the company made $1,80
djyliett [7]

Answer:

Step-by-step explanation:

Total profit = $ 1,800,000

4x + 3x + 2x = $ 1,800,000

9x =$ 1,800,000

x =  1,800,000/9

x = $ 200,000

President's share= 4x = 4* 200,000 =$800,000

Vice president's share = 3x = 3 * 200,000 = $ 600,000

Financial officer's share = 2x = 2 * 200,000 = $ 400,000

Step-by-step explanation:

(3x² + 6x) + (8x + 16) = 0

3x(x+2) + 8(x+2) = 0

(x+2)(3x+8) = 0

x = -2  ,  x = -8/3.
