For each equation, determine if x=2 is a solution . Explain or show your reasoning. 1. -2(x - 4) = 4
2. 26/x= 13
3. -3.8x = -7.4
4. 4(x-1) - 3(x-2) = -8

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

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.  

the answer will be b x² +x-1
