When abc was dialed by a scale factor of 2, centered at the origin, the result was its image a'b'c' shown on the coordinates plane below. the vertices of a'b'c' are a'(-4,4), b'(-4,6), and c'(2,4)

what are the coordinates of the vertices of abc?

explain how you determined the coordinates of the vertices of abc?

are abc and a'b'c' congruent to each other, similar to each other, or neither? explain how you determined your answer

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.
