The graph of y = -2x + 3 is a straight line
Its slope is - 2
Its y-intercept is + 3
To draw the line you can use these two points (0,3) and (3/2 , 0)
This line does ont pass through the third quadrant. It comes downward from the second quadrant, touches the y-axis at y =3, continues on the rirst quadrant, touches the x-axis at x = 3/2, and contiues into the fourth quadrant.
Graph of its inverse
Exchange y and x in the given function and solve for the new y
x = - 2y + 3 => y = - x/2 + 3/2
It is also a straight line;
Its slope is -1/2
Its y-intercept is 3/2
It is also in the second, first and fourth quadrant
Use these two points to draw the line (0,3/2) and (3,0).
You do not need to know to draw this, but the inverse of a function is its reflection through the line y =x.
Answer: If one is constructing a phylogeny of reptiles using DNA sequence data of birds, mammals, amphibians or fish, the suitable outgroup to be used are mammals due to the time of divergence from other group of organisms.
Explanation: Phylogeny is used to determine evolutionary relationship between items or organisms. A phylogenetic tree is a graphical illustration of phylogenetic relationship. In phylogeny, an outgroup represent an organism that is more distantly related to other group of organisms.
In a phylogenetic tree, outgroup stands alone. It shows that the time of divergence of that particular organism is far from other group of organisms. Outgroup is used to root a tree and sometimes represent a group that is more ancestral on a tree.
It should be noted that differences in the DNA sequences of the organisms under consideration will determine which organism will serve as the outgroup.
Answer:
Blood enter the right atrium of the heart via the vena cava (superior and inferior)
The right atrium contracts to push the blood into the right ventricle through the triscupid valve
The contraction of the right ventricle pushes the blood through the pulmonary valve to the pulmonary artery which carries it to the lungs to be oxygenated
After oxygenation, the pulmonary vein brings blood to the left atrium
Contraction of the left atrium pushes the blood through the mitral valve into the left ventricle
The left ventricle contracts to push the blood through the aortic valve, into the aorta, which carries the blood through the body.
Explanation:
During the day the sun burns up and the sand soaks up the heat causing a oven effect.
<span>While at night the wind will blow, and the sun is gone so the effect is like garages in the night. A great way to Yahoo or google search is "Desert climate and effects."</span>
