We have received $ $30,000$ to invest. We want to invest some in an insured bank account with an expected average return of $4\%$ and some in an uninsured account that has an expected return of $12\%.$ We have been given instructions that we must invest at least $ $8,000$ in the insured account while we must not invest more than $ $14,000$ in the uninsured account. If we want a minimum of $ $1,800$ in annual returns, draw the region of feasibility for our investments.

List each corner$/$vertex point $($answers should be rounded to two decimals places, but order does not matter$).$ Please use x as the amount in the insured account.
