-5x + 3x +9 = ax + 4 +b

a=−b−2x+5/x

Step-by-step explanation:

Step 1: Flip the equation.

ax+b+4=−2x+9

Step 2: Add -b to both sides.

ax+b+4+−b=−2x+9+−b

ax+4=−b−2x+9

Step 3: Add -4 to both sides.

ax+4+−4=−b−2x+9+−4

ax=−b−2x+5

Step 4: Divide both sides by x.

ax/x=−b−2x+5/x

a=−b−2x+5/x

idk

step-by-step explanation:

maybe try   if it is work from a book, if not try

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
