Some countries implement income taxes on a progressive scale. Meaning, part of your income can be taxed at one rate and part of your income can be
taxed at a different rate.
Write a piecewise function that represents the following tax scale.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.

leave feedback if u need : )

y - 25 = 2 ( x - 10 ) should be the answer

4y - 6 + y^2 - 9 = y^2 + 4y - 15

y^2 term

total of 3 terms when simplified
