For problem 1, when you solved for x, you only got solution x=3. you cannot plug in another number for x. when you solve for the variable and got x=#, that means there is only one solution, which is the number you ended up with

why can't you?

step-by-step explanation:

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

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.  

answer: y=0 if that is what u r looking for
