In planning her retirement, Liza deposits some money at 3% interest, with twice as much deposited at 4.5%. Find the amount deposited at each rate if the total annual interest income is $2400.

Step-by-step explanation:

.03x + .045(2x) = $2040

        .12x = $2040  

           x = $17,000 at 3%  and $34,000 at 4.5%  

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
