If you're looking for the solution to the system of equations, here's how we solve using substitution
We know that y = x - 1, so we can plug that into the first equation giving
2x - 3(x-1) = -1
Now distribute the 3 giving 2x - 3x + 3 = -1. After combining like terms we get -x + 3 = -1. Now subtract 3 from both sides, -x = -4, and multiply both sides by -1 to make x positive. x = 4
Now we can plug that into the second equation to get y
y = x - 1, and we know that x = 4, so y = 4 - 1, y = 3. The solution is (4, 3)
Answer:
below
Step-by-step explanation:
l = large no
s = small no
l=s+13
l+s = 67
s+13+s = 67
2s+13 = 67
2s = 54
s=27
l= 40
The population of the Bulbul birds at the start of the migration season is 1800.
<h3>
Exponential function</h3>
An exponential function is given by:
y = abˣ
Let y, x are variables, a is the initial value and b is the multiplication factor.
Let P be the population of the bird t days since the start of the migration season.
