Determine which situations best represent the scenario shown in the graph of the quadratic functions, y = x2 and y = x2 + 3. Select all that apply.

The quadratic function, y = x2, has an x-intercept at the origin
The quadratic function, y = x2 + 3, has an x-intercept at the origin
From x = -2 to x = 0, the average rate of change for both functions is positive
From x = -2 to x = 0, the average rate of change for both functions is negative
For the quadratic function, y = x2, the coordinate (2, 3) is a solution to the equation of the function.
For the quadratic function, y = x2 + 3, the coordinate (2, 7) is a solution to the equation of the function.

Successful implementation of a new system is based on three independent modules. module 1 works properly with probability 0.96. for modules 2 and 3, these probabilities equal 0.95 and 0.90. compute the probability that at least one of these three modules fails to work properly.

How do you use the elimination method for this question? explain, because i really want to understand!

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)) =
