Evaluate the expression for the given values of the variables. a2-b for a = 9 and b = 5
When a = 9 and b = 5, the expression is equal to

Fasst

a²-b

(9)²-(5)

81-5

76

therefor, your answer is 76

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
