Answer:
see below
Step-by-step explanation:
Part A
Since the lines goes through the point (0,0) the graph is proportional. We can find the rate of change by take the price of corn and dividing by the number of bushels
24/3 = 8 dollars/ bushel
Part B
Previous Year Number of Bushels Price of Corn (dollars)
3 21
6 42
9 63
12 84
We can find the rate of change for the previous year by using the slope formula
m = (y2-y1)/(x2-x1)
m = (84-63)/(12-9)
=21 / 3
= 7
The previous year was 7 dollars per bushel
The increase was 8-7 = 1 dollar per bushel

Answer:
The solution to the system of equations (x, y) = (2, 4) represents the month in which exports and imports were equal. Both were 4 in February.
Step-by-step explanation:
We're not sure what "system of equations" is being referenced here, since no equations are shown or described.
__
Perhaps your "system of equations" is ...
f(x) = some equation
g(x) = some other equation
Then the solution to this system of equation is the pair of values (x, y) that gives ...
y = f(x) = g(x)
If x represents the month number, then the solution can be read from the table:
(x, y) = (2, 4)
This is the month in which exports and imports were equal. Both numbers were 4 in February.
Answer:
<S = 151 degrees
<DCE = 52 degrees
Step-by-step explanation:
The sum of interior angle of pentagon is 540 degrees
5x+2+7x-11+13x-31+8x-19+10x-3 = 540
43x - 62= 540
43x = 540+62
43x =602
x = 602/43
x = 14
get <S
<S = 13x-31
<S = 13(14)-31
<S = 182-31
<S = 151 degrees
2) The sum of interior angle is the exterior
180-7x+2+180-4x-33 = 9x-31
360-11x-31 = 9x - 31
360 = 9x+11x
360 = 20x
x = 360/20
x = 18
<DCE = 180 - 7x - 2
<DCE = 180-7(18)-2
<DCE = 180-126-2
<DCE = 180-128
<DCE = 52 degrees
