Write the solution of the inequality in set builder notation 7-3d> 28

{ x :  x is a real number less than -7 }

Step-by-step explanation:

Given inequality,

        ( a > b ⇒ na < nb if n < 0 )

That is, all real numbers less than -7,

Now, in set builder form we state the properties of the elements of the set by using the mathematical symbol under the flower bracket {} .

Thus, the required set would be,

{ x :  x is a real number less than -7 }

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.
