Write an inequality that represents the following phrase: 5 multiplied by the sum of x and 2 is at most 30

the symbol for inequality is ≤ or ≥.

Here the expression is 5(x+2) ≤ 30.

This means that 5 (x+2) is not more than 30.

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.  

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
