The equation is: (y+3)/(-1+3) = (x-5)/(3-5);
Then, (y+3)/2 = (x-5)/(-2);
Finally, y+3 = -x+5;
y = -x + 2;
<span>0.75x + 0.5y = 25,
if x=0, </span>⇒0.5y = 25, ⇒y=50

<h2>
Answer:</h2><h2>The number of animals of the species will be left in 2025 = 2519 animals</h2>
Step-by-step explanation:
The number of animals of a certain species in 1980 = 20000
The rate of decrease each year = 4.5 %
The number of animals left in 2025 = ???
The number of years between 1980 and 2025 = 45
By formula of depreciation,
where Pn is the population in 2025
P is the population in 1980
R is the rate of decrease in population
Substituting the values in the equation, we get
=
=2518.7 = 2519 species.
