First off, 23+12 isn't 45.
Anyways,
Part A, graphing should be pretty simple, just match the corresponding values together as shown by the table on the left. For example, for the crop size that says "200," go up to where the value is seven, and mark it.
The function is also not that hard. Make "x" equal the value of the crop size. (Square yards) Thus for "x" crop size, the function B(x) = 3.5/100.
Part B<span>
W(x) = 60*x
</span>For the completing the table, just plug in some
values for "x" (remember "x" is "Bushels of corn in a
shipment") like 1, 2, 3, 4 etc, and write the corresponding output next to
it.
Part CThe given information literally tells you the
answer. P(x) = 4x. That's ur function. So for the graph, say "x"
("Bushels of Corn") is 1, than the corresponding "y" value
("Selling Price") is 4, since P(x) = 4*x.
<span>
As for completing the table, once again, just write in
several values, geez. For example, "Bushels of Corn" = 5, than
"Selling Price" = 20.
The function basically is the key to all the answers. </span>
Part DAlright, remember, once you get the function,
you have all the answers. 5 Bushels of corn equals 14 gallons of ethanol, so
the function is <span>
<span>E(x) = 14/5. (And remember, the "x" value is "bushels of corn")
</span></span>
The table and graph are easy to do, since you know the function, however the "y" axis values on the graph are kind of challenging to deal with, but I have faith that you can estimate and mark the values close enough.<span>
</span>
Here's my best explanation for Part E,<span>
Proportional relationships have graphs that always pass
through the origin of a graph, while non-proportional graphs don't. And also,
proportional relationships always have consistent ratios, while
non-proportional relationships don't. And for their equations, proportional
relationships equations are always one step, (Ex: y = 5x) while non
proportional equations are two-step equations, which means they contain a
constant value that is added or subtracted on the left side. (Ex: y = 3x - 12)</span>
