X is the son's age = 20

1 + 3x  
= 1 + 3(20)
= 1 + 60
= 61

so father's age = 61
son's age = 20

What is the equation of the following line? (1,7) (0,0)
elena-s [515]

Anytime x = 0 in a point the y intercept is immediately defined.

y = mx + b The y intercept is b

y = 0 + b

0 = 0 + b

b = 0

What you know so for is

y = mx + b

y = mx since b = 0

7 = m*1

m = 7

The answer is y = 7x <<<<<<Answer.

An initial population of 415
slamgirl [31]

Answer:

The exponential function to model the duck population is:

f(n)=415*(1.32)^n, where:

x is the duck population

n is the number of years

Step-by-step explanation:

In order to calculate the duck population you can use the formula to calculate future value:

FV=PV*(1+r)^n

FV=future value

PV=present value

r=rate

n=number of periods of time

In this case, the present value is the initial population of 415 and the rate is 32%. You can replace these values on the formula and the exponential function to model the duck population would be:

f(n)=415*(1+0.32)^n

f(n)=415*(1.32)^n, where:

x is the duck population

n is the number of years
