19. The population of Jose's town in 1995 was 2400 and the population in 2000 was 4000. Let x represent the number of years since 1995. Write a linear equation, in slope-
intercept form, that represents this data.

for #19 i got y=320x+2400
i need help with number 20.

20. use the equation in #19 to predict the population in jose’s town in 2010.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

investment b is an ordinary annuity with $3,909.64 in the account after one year.

step-by-step explanation:

c.

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
