Ryan tried to solve the system of equations shown below.

{3x−2y=11−1.5x+y=−4He concluded that the system has no solution. Which is the best evaluation of Ryan's conclusion?

A
He is correct. If the second equation is multiplied by 2 and added to the first equation, the result is 0=3 , which means the system has no solution.

B
He is incorrect. If the second equation is multiplied by 2 and subtracted from the first equation, the result is 6x−4y=19 , which has infinitely many solutions.

C
He is correct. For any positive value of x , the corresponding value of y is negative, which means the system has no solution.

D
He is incorrect. Both equations describe lines that have infinitely many solutions.

Someone answer asap 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)) =
