Answer:
D
Step-by-step explanation:
the center is (0,8)
(to solve this just flip the signs on the constants being added to x and y (there is an invisible constant of 0 being added to the x))
the radius is 7 (or √49)
Normal price for 5 pages: number of pages times the price per page
(5)*($8.75) = $43.75
Discounted rate: $8.75 - $1.45 = $7.30
Discounted price for 5 pages:
(5)*($7.30) = $36.50

Step-by-step explanation:
Answer:
x = 16 when y = 40
Step-by-step explanation:
as y is directly proportional to x:
y = x
y = k x .........k is here constant.
15 = k * 6
k = 15/6
k = 5/2
Here constant, k is (5/2)
So when y = 40
y = k x
40 = (5/2)x
x = 40(2/5)
x = 16
