An advertising agency has found that when it promotes a new product in a city the weekly rate of change R of the number of people who are aware of the promotion follows a linear pattern. The weekly rate of change R of people who are aware of the promotion x weeks after it is introduced is described by the equation R = 1800-60x. Find the x- and R-intercepts and then graph the function on a viewing window that is meaningful in this application. What is the x-intercept? 30 (Type an integer or a fraction.) What is the R-intercept? 1800 (Type an integer or a fraction.) Choose the most appropriate viewing window boundaries for the function. OA. [0,60] by [1740,1800] OC. [0,1740] by [60,1800] OB.

A salesperson is paid a base salary of $2000 a month plus a 4% commission on their sales of x dollars. Write a linear function P(x) that represents the salesperson's total monthly pay, P (in dollars) in terms of their sales x. Then use that linear function to determine the value of x that will result in a monthly pay of $3120. Enter just the value of x that will result in a monthly pay of $3120 in the answer box. x=? dollars
In 2000,53 % of the residents in a large city regularly used newspapers for getting news and this has decreased at an average rate of approximately 1.1 % per year since then. Find a linear function in slope-intercept form that models this description. The function should model the percentage of residents,Upper P left parenthesis x right parenthesis comma who regularly used the news outlet x years after 2000.
Tom is driving to Seattle. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes). Tom has 54 miles to his destination after 49 minutes of driving, and he has 33.2 miles to his destination after 75 minutes of driving. How many miles will he have to his destination after 91 minutes of driving?
Members of a local band hold a bake sale to raise money. They sell their baked goods on blue and white paper plates. Each blue plate costs $5 and each white plate costs $3. The band raises $430 from their bake sale. Elise wants to sketch a graph of the linear function that relates the possible number of blue plates sold, x, to the possible number of white plates sold, y. Which THREE statements are TRUE regarding the graph that Elise will sketch? A) The graph will not have an x-intercept. B) The graph will decrease over its entire domain. C) The graph will show only x- and y-values that are positive. D) The graph will have an x-intercept of 86, the maximum possible number of blue plates sold. E) The graph will have a y-intercept of 143, the maximum possible number of white plates sold. F) The graph will show that as the number of white plates sold increases, so will the number of blue plates sold.
