Two florist purchased flower bouquets and vases at the same store. the first florist bought 2 flower bouquets and 2 vases for a total of $12.50. the second florist bought 8 flower bouquets and 2 vases for a total of $29.00. let b represent the cost of one flower bouquet and v represent the cost of one vase. write and solve a system of equations to find the price of each type of arrangement. show all work! for all your !

answer: the equation matches the regression

step-by-step explanation:

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.
