The table below shows the relationship between the number of hours a computer programming project takes and the total cost charged by a programmer
Hours (x): 4,6,8,10
Cost (y): 575,825,1075,1325
Write a linear equation in slope-intercept form that describes the relationship in terms of c and y.

How much does the programer charge per hour?

How much does the programmer charge for a 13-hour-long project?

Write an equation in standard form for a line with a slope - 6 that includes the point (3,2).

Find the cosine function that is represented in the graph.

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)) =

21 type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar. the solution set of n2 - 14n = -45 is { (separate the solutions with a comma)
