What is the value of the discriminant, b2 4ac, for the quadratic equation O = x2 - 4x + 5, and what does it mean it
about the number of real solutions the equation has?
O The discriminant is -4, so the equation has 2 real solutions.
© The discriminant is -4, So the equation has no real solutions.
The discriminant is 35, so the equation has 2 real solutions.
O The discriminant is 35, so the equation has no real solutions.

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)) =

Which value would be a solution for x in the inequality 47-4x< 7

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5
