The daily cost of hiring a plumber, y,to work x hours on a repair project can be modeled using the linear function y=55x +75. the plumber charges a fixed cost of $75 plus sn additional cost of 55 per hour. the plumber works a maximum of 50 hours per week. for one week of work what is the domain of the function for this situation

Domain for the given situation is,

Explanation:

Here, x represents the number of hours

and y represents the daily cost of hiring a plumber.

To repair project can be modeled using the linear function is:

y = 55x + 75

Since, it is also given that the plumber works a maximum of 50 hours per week.

Domain of the linear function is the complete set of possible values of the independent variable(i.e x)

⇒Domain of the given linear function for one week is;

 or

In interval notations  [0, 50]  where x is the number of hours.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
