What is one difference between yearly and monthly budgets?
a.
yearly budgets show a greater degree of planning, so it is appropriate to plan expenses more strictly and in a more detailed fashion in a yearly budget.
b.
monthly budgets should focus on the short term, so it is not appropriate to consider planned but future expenses (such as a vacation) in a monthly budget.
c.
yearly budgets are a better view of your financial goals, so you should work very hard to avoid changing yearly budgets.
d.
there is more uncertainty as you plan further ahead, so a yearly budget needs more room to account for unplanned expenses than a monthly budget does.

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
