If the distance from the center of dilation to one line is 9, and the distance from the center of dilation to a parallel line is 2.5, what scale factor should be used to map the first line onto the second?(1 point) The scale factor is the distance of the mapped image times the distance of the original image, 2.5×9=22.5. The scale factor is the distance of the original image over the distance of the mapped image, 92.5=3.6. The scale factor is the distance of the mapped image over the distance of the original image, 2.59≈0.28. The scale factor is equal to half of the distance to the original image, 92=4.5.

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)) =
