The distances (y), in miles, of two cars from their starting points at certain times (x), in hours, are shown by the equations below: car a: y = 52x + 70 car b: y = 54x + 56 after how many hours will the two cars be at the same distance from their starting point and what will that distance be? 6 hours, 420 miles 6 hours, 434 miles 7 hours, 420 miles 7 hours, 434 miles

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
