Use substitution to solve the system of linear equations. in your final answer, include all of your work.

No solutions

Step-by-step explanation:

Substitute instead of into the second equation:

Use distributive property to open the brackets:

This equality is false (3 is not equal to -3), so the system of two equations has no solutions.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

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.
