A tank full of water is leaking at a constant rate for 30 minutes. The equation
y=-9x + 500
gives the amount of water in the tank, where yis the number of liters and xis
the number of minutes since the tank began to leak. Which statement is true?
O A. There were 500 liters in the tank when the leak started, and it is
decreasing by 9 liters per minute.
B. There were 9 liters in the tank when the leak started, and it is
increasing by 500 liters per minute.
C. There were 9 liters in the tank when the leak started, and it is
decreasing by 500 liters per minute.
O D. There were 500 liters in the tank after 30 minutes, and it is

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
