#27 would you try different t values to find h? or not?

represents the number of households that own ...blah... years 1996. So is the number of households in the year 1996; we're told that (since is the number of households in millions).

At the end of each year, this number increases by 4.85%, i.e. a factor of 1.0485. This means after 1 year, the number of households is

After 2 years, or 1 year after the first year elapses, the number is

After 3 years,

and so on, with the general pattern of

This is the function you're asked to find.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

the aswere is the one with all 8's and the second one is with the 10,8 and 6
