  $4917.50

Step-by-step explanation:

Using the method in expected for a table of this nature, the tax is ...

  tax = 2% × $3000 + ...

     3% × ($5000 -3000) + ...

     5% × ($17000 -5000) + ...

     5.75% × ($90000 -17000)

  = $60 +60 +600 +4197.50

  tax = $4917.50

The attached spreadsheet simplifies each row of the table to a formula of the form ...

  tax = rate × income - discount

The final value of tax is the maximum of the values on the rows of the table when they are computed this way.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

irrational, cannot
