Step-by-step explanation:

determine the amount of an investment if 700$ is invested at an interest rate of 8% compounded monthly for 9 years

those are the answers that i have thought of.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
