In the first paragraph, why is the phrase "little mountain escape" in quotation
marks?
O to stress the fact that the Biltmore was to provide a vacation spot for friends
to indicate that the Biltmore was built in the midst of the mountains
to highlight the goal the Vanderbilt's had in building the Biltmore
to provide a contrast to the actual enormity of the Biltmore

D. To provide a contrast to the actual enormity of the Biltmore

Step-by-step explanation:

Usually, when something is in "quotes", it's used to indicate sarcasm, emphasis, or a direct quote. This indicated emphasis.

B & C

Part 6 : C

Part 7 : y = 4x + 19

Part 8 : 1/2 , -10 (They try to trick you here with a + sign, make sure to add the negative symbol)

The answer is 12x + y = 185

The common formula for a two variable linear equation is: ax + by = r

The lab starts with 185 dishes which is y-intercept:

ax + by = 185

The number of dishes used per day is 12 which is slope:

12x +by = 185

Therefore, the two variable linear equation for this example is 12x + y = 185.

To solve for the variable cost:

11 - 5 = 6

3.24 - 2.70 = 0.54

0.54 / 6 = 0.09 per print

To solve for the fixed cost

0.09 x 5 = 0.45

2.70 - 0.45 = 2.25 

y = 2.25 + 0.09x

y = 2.25 + 0.09(5) = 2.25 + 0.45 = 2.70

y = 2.25 + 0.09(11) = 2.25 + 0.99 = 3.24

y = 2.25 + 0.09(20) = 2.25 + 1.8 = 4.05
