- . Marriage Rate The marriage rate per 1000 unmarriedwomen for the years 1987–2014 can be modeled bythe function 132x + 1000y = 9570, where x is thenumber of years after 1980. During what year doesthe equation indicate the marriage rate will be 4.29?(Source: National Vital Statistics Report 2010)arrow_forward.

Callie's progress through her novel can be modeled by the function p(d) = -25d +318, where p(d) represents the number of pages remaining to be read and d is the number of days since receiving the book. Elena's progress through her novel is modeled by the graph below. АУ # Pages Left 400 350 300 250 200 * 150 100 50 (3275) (8,75) 2 3 4 5 6 7 # Days Part A. Which student's novel has more pages to read? 8 9 10 11 Part B. Assuming they both continue to read at a constant rate, which student will complete their novel first?arrow_forwardA group of farmers collected data on the number of foxes and the number of rabbits seen on their properties per week. Ths scatter plot below shows the data they collected. Th farmers used the equation y = -3x + 100 to model the data collected. Based on the equation, which statement is true? A. Each additional fox is associated with 3 more rabbits. B. Each additional fox is associated with 3 fewer rabbits. C. Each additional fox is associated with 100 more rabbits. D. Each additional fox is associated with 100 fewer rabbits.arrow_forward
