Joy co. allocates overhead expenses to all departments on the basis of floor space (sq. ft.) occupied by each department. this year total overhead expenses were $22,000. department a. occupied 15,000 sq. ft., department b. 18,000 sq. ft., and department c. 9,000 sq. ft. the amount of overhead allocated to department b is (round to the nearest dollar):

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
