Select 3 of the below equations that represent the line that has a slope of -2 and a y-intercept of 5 y+2= 5x
y-5 = -2x
y+5 = -2x
2x+y =5
X+2y = 5
2x + y = -5
y= 5x-2
y = 2x+5
y = -2x+5

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Describe the 2 algebraic methods you can use to find the zeros of the function f(t)=-16t^2+400.

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)) =
