Mr. Hamilton decorates his U. S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 3/4 feet long. Each president picture is 6 feet inches wide.

8 pictures

Step-by-step explanation:

Wall length = 9.75 ft

Window length = 5.75 ft

Length of wall available for pictures:

9.75 ft - 5.75 ft = 4 ft

1 ft = 12 in

4 × 12 in = 48 in

Each picture is 6 in wide.

48 in / 6 in = 8

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
