The graph shows the prices of different numbers of bushels of corn at a store in the current year. The table shows the prices of different numbers of bushels of corn at the same store in the previous year.

A graph shows the Number of Bushels on the x-axis and the Price of Corn in dollars on the y-axis. The x-axis scale is shown from 0 to 14 at increments of 2, and the y-axis scale is shown from 0 to 98 at increments of 14. A straight line joins the ordered pairs 2, 14 and 4, 28 and 6, 42 and 8, 56 and 10, 70 and 12, 84.

Part A: Describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value.
Part B: How many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? Show your work.

Answers

Answer:Part A:8  Part B:$1

Step-by-step explanation:

Part A: 7 dollars  

- The graph shows that 2 bushels is 14 dollars,  because the graph has a straight line, the rate remains constant you must divide the sides by two to find the amount for one bushel which would be 7 dollars.

- And to double check you would divide 28 by 4, 42 by 6, 56 by 8, 70 by 10, 84 by 11, and 98 by 12. they all equals 7 dollars So, the equation would be y = 7x.

- 7 can be known as the slope and  rate of change.

Part B:2 dollars

- The years before show 2 bushes was 10 dollars

-so you would divide 10 by two you would get five  To double check you would do the same thing with 20 by 4, 30 by 6 and 40 by 8, and they all equal 5 dollars.

-if you use this answer be sure to reword it so you dont get copy write and integrity. have a great day or night.

Use slope = rise/run.

the answer is y=1/2 because you can use the formula k=y/x to the find the constant value so if you take the two numbers from the second column you would take the y which is 1 out it on top and then 2 which is x on bottom which would look like 1/2 which gives you you’re answer.

Answers

Answer:

this is algebra remember algebra rules and thing really hard

Step-by-step explanation:

The formula for the height of the trapezoid will be h = 2A/(c+ d).

What is surface area?

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

In another meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.

Given a trapezoid with side lengths c and d and perpendicular distance as h

So, the area formula will be

A = (1/2)h(c + d)

Multiply both sides by 2

2A = h (c + d)

Divide by c + d into both sides

2A/(c + d) = h

Hence "The formula for the height of the trapezoid will be h = 2A/(c+ d)".
