A farmer has a grain bin with 4,000 cubic feet of barley in it. He uses 800 cubic feet to feed his herd of cows. The next day, he buys 800 cubic feet of barley and puts it into the grain bin. How many cubic feet of barley are in the grain bin now? A) 2,400
B) 4,000
C) 4,800
D) 5,600

b- 4,000

Step-by-step explanation:

B

Step-by-step explanation:

It is B because

4000-800=3200

then

3200+800=4000

so he answer is B.4000  

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)
