1.75x + 1.25y = 2.75
7x + 5y = 9

How many solution(s) satisfy the system?
Choose the correct response.
A.
None. Since 119, there is no solution.

B.
Infinitely many. Since 0 = 0, there are infinitely many solutions.

C.
One. Since x =and y = 0, there is one solution.

D.

Two. Since (11) and (0.9) belong to both equations, there are two solutions.

Someone answer this asap rn for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
