Evaluate the expression when m=9 and n=4.
6m-n
X
?
6m -4

50

Step-by-step explanation:

6m-n

Let m = 9 and n = 4

6*9-4

Multiply first

54-4

Then subtract

50

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
