$1000 is deposited into a saving account interest is compounded annually after 1 year the value Of the account is 1,020 after 2 years the value of the account is 1,040.40 thaï scénario can ne reprensented by an exponential function of the form f(x)=1000(b) where f(x) is the amount In the saving account and x is time in years what is the value of B

stops on an even number.

hope this !

let me know

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
