Answer:
d = 5
Step-by-step explanation:
-7d = -35
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, d. Divide - 7 from both sides:
(-7d)/-7 = (-35)/-7
d = -35/-7
d = 35/7
d = 5
d = 5 is your answer.

Answer:
The crossover point for Time 
Step-by-step explanation:
From the question we are told that
The total rooms rented for the year is 
Time's fixed cost is r = $61,000
Time's variable cost is 
$12.5 per room
Duffy's Maid Service fixed cost is 
$25,000
Duffy's Maid Service variable cost is 
$18.00 per room
The cross over point for Time is mathematically represented as
substituting values
Answer:
+2
Step-by-step explanation:
The given equation, r = -3 + 5 sin theta, includes a sine term whose max value is +5 and whose min value is -5. We are interested in finding the max value that r can have. To obtain this, take that constant term, -3, and add teh max value of the sine function, which is +5. Net: 5 - 3 = 2.
The max value that r = -3 + 5 sin theta can take on is +2.
