The rabbit population in a forest begins with 20 rabbits and increases steadily by 40 rabbits every month. The equation for rabbit population, R, in terms of time, in months, t, is?

R = 40t + 20

Step-by-step explanation:

We need to use the equation y = mx + b to solve this because it's linear.

"m" is the slope, or the rate. Here, we know that the population increases by 40 rabbits per month, which means m = 40.

"b" usually means that fixed, initial amount. Here, we know that the population begins at 20 rabbits, which means b = 20.

Plug these in:

R = mt + b

R = 40t + 20

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
