A person plans to invest up to $10,000 in two different interest-bearing accounts, account X and account Y. Account Y is to contain at least $ $1000$ . Moreover, account X should have at least twice the amount in account Y. Graph the system of linear inequalities describing the various amounts that can be deposited in each account.

Final Answer :

B

Explanation :

We can represent the amount invested in Account Y as $y$ and the amount invested in Account X as $x$. Then we have two constraints:

$y≥1000$

$x≥2y$

We also know that the total amount invested cannot exceed $10,000$, so we have the constraint:

$x+y≤10,000$

Graphing these on a coordinate plane, we get a shaded feasible region (bounded by the three lines). Only option B correctly represents this feasible region.
