Convert to the standard form:-
x^2 + 14x + y^2 - 6y = -42
(x + 7)^2 - 49 + (y - 3)^2 - 9 = -42
(x + 7)^2 + (y - 3)^2 = -42 + 49 + 9 = 16
r^2 = 16 so r = 4 and the diameter = 2*4 = 8 Answer
Answer:
y = $2.5x, where "x" is the number of drinks.
Step-by-step explanation:
Step 1: Let "x" be the number of drinks and "y" be the cost.
Step 2: The cost of a drink = $2.5
Now we can find the cost for "x" drinks.
y = $2.5x.

Answer:
so... one cot is $91 and they need 4 for one cabin. so that's 4 times $91 and that's $364.
they have 14 cabins and cots for one cabin are $364. so cots for 14 cabins are 14 times $364. Therefore new cots will cost $5096.
