The image of a triangle after it has been dilated with a center of dilation at the origin has vertices at A prime(12, β6), B prime(β24, β12), and C prime. If the pre-image of B prime, point B, has coordinates of (β18, β9) and the pre-image of C prime, point C, has coordinates of (β13.5, 18), which statements are true? Check all that apply. The coordinates of C prime are (27, 18). The coordinates of C prime are (β18, 24). The scale factor is 1 and one-third. The scale factor is 1 and one-fifth. The scale factor is Three-fourths. The coordinates of A are (16, β8). The coordinates of A are (9, β4.5).

Someone answer this asap rn for ! a discount storeβs 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)) =
