Solve the inequality for x: 2x+3<23

X<10

Steps:

Move constant to the right

2x<23-3

Subtract the numbers

2x<20

Divide both sides by 2

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

ab will be equal to
