A cleaning company charges $200 for each office it cleans. The fixed monthly cost of $450 for the company includes telephone service and the depreciation on cleaning equipment and a van. The variable cost is $50 per office and includes labor, gasoline, and cleaning supplies (a) Write a linear cost function representing the cost C(x) (in $) to clean x offices per month.

(b) Wnte a linear revenue function representing the revenue R(x) (in $) for cleaning x offices per month.

(c) Determine the number of offices to be cleaned per month for the company to break even.

(d) If 21 offices are cleaned, will the company make money or lose money?

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

3 is greater then both of those numbers

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
