Write a linear function f with f (5)=7 and f (-2)=0

20

Step-by-step explanation:

because 10 plus 10 is 20

The slope is (7-0)/(5 - -2) = 7/7 = 1

Using (-2,0) the intercept is B = y - mx

                                               = 0 - (1)(-2) =

                                                  0 +2 = 2

y  = x +2

Step-by-step explanation: If i got it wrong, please forgive me and let me know. also i hope i helped you!

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.
