3lines are shown. a line with points p, r, n intersects a line with points o, r, m at point r. a line extends from point r to point l in between angle m r p.
marcus states that angle orp and angle lrp are a linear pair. which best describes his statement?

he is correct. the angles share a common vertex so they are a linear pair.
he is correct. the angles share a common ray so they are a linear pair.
he is incorrect. angle orp does not form a linear pair with another angle in the diagram.
he is incorrect. ray ro and ray rl are not opposite rays.

Harold wrote this equation to model the level of water in a pool over time. the variable x represents time in hours. f(x) = 3,500 - 225x which statements about the situation are true? check all that apply. the water level is rising. the water level is falling. the initial level of water in the pool was 3,500 units. the initial level of water in the pool was 225 units. the pool was empty after 14 hours. the water was 2,600 units high after 4 hours.

Let us imagine that the number of automobile accidents in a certain region are related to the regional number of registered automobiles in tens of thousands (b1), alcoholic beverage sales in $10,000 (b2), and decrease in the price of gasoline in cents (b3). furthermore, imagine that the regression formula has been calculated as: y = a + b1x1 + b2x2 + b3x3 where y = the number of automobile accidents, a = 7.5, b1 = 3.5, b2 = 4.5, and b3 = 2.5 calculate the expected number of automobile accidents for a football weekend if the region has 25,000 registered vehicles, $75,000 worth of beer is sold, and a gas war causes a 10 cent drop in a gallon of gas.
