Solve the system of linear equations by substitution.
6x – 9=y
y=-3.7

x=0.88

y= -3.7

Step-by-step explanation:

-3.7=6x-9

5.3=6x

0.88=x

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.
