The amount of money in harold's savings account is inversely proportional to the number of bills he has to pay each month. if x represents the number of bills he has to pay each month, and y represents the money in his savings account, find the following: a- use the equation y = k/x to find k, the constant of variation; if harold has $209 in his bank account when he has 3 bills to pay. b- if harold has 5 bills to pay this month, how much money will he have in savings? c- if harold's wife sylvia sees only $69.67 in their savings account, about how many bills can she assume they had to pay this month?

Find the center and the radius of the circle with the equation: x^2-2x+y^2+4y+1=0?

Can you me find the missing length. i attached an image.

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
