alexandr402 [8]

Answer:

a=-\frac{b}{2x}

Step-by-step explanation:

The equation of a quadratic function is given as:

ax² + bx + c = 0

To get the equation for a, we have to make a the subject of formula:

x=-\frac{b}{2a}\\\\multiply\ both\ sides\ by \ 2a:\\\\x*2a=-\frac{b}{2a}*2a\\\\2ax=-b\\\\Divide\ through\ by\ 2a\\\\2ax/2a=-b/2a\\\\a=-\frac{b}{2x}

How long will it take a population of 550 moose to double if 25 offspring are born and 14 moose die on average per year?
Sergio039 [100]
If 25 offspring are born and 14 moose die per year that means every year the number of moose increases by 11.

550 + 11x = 550*2
(x: how many years taken to double the number of moose)
550 + 11x = 1100
11x = 550
x = 50 years
