Since slope is calculated using the formula m = startfraction v 2 minus v 1 over x 2 minus x 1 endfraction, the slope of both lines is equivalent to it is given that the lines are parallel, and we calculated that the slopes are the same. therefore, parallel lines have the same slopes. startfraction v minus z over w minus x endfraction startfraction w minus x over v minus z endfraction startfraction v minus z + b over x minus z + a endfraction startfraction w minus x + a over v minus z + b endfraction

You invested $5000 between two accounts paying 4% and 9% annual interest, respectively. if the total interest earned for theyear was $350, how much was invested at each rate? $was invested at 4% andwas invested at 9%.

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)) =

25 ! i need asap! ! ill mark brainliest!
