Find the xx-intercept of each line defined below and compare their values. \text{\underline{equation of line a: }} equation of line a: x-y= x−y= \,\,1 1 \underline{\text{select values from line b: }} select values from line b: xx yy -3−3 00 -2−2 -1−1 -1−1 -2−2 00 -3−3 the xx-intercept of line a is and the xx-intercept of line b is . therefore the xx-intercept of line a is the xx-intercept of line b.

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)) =
