25 POINTS!!!!!
The daily cost of hiring an electrician, y, to work x hours on a repair project can be
modeled using a linear function. The electrical charges a fixed cost of $45 plus an
additional cost of $65 per hour. The plumber works a maximum of 8 hours a day.
For one day of work, what is the range of the function for the situation?
A. 0 B. 45 SX565
С. 0 D. 45 < y < 565

Answer 1

Answer:

45 < y < 565

Step-by-step explanation:

y = 45 + 65x  where x is the number of hours

We want the range or the values that y can take

The plumber can work 0 to 8 hours

Let x = 0

y = 45+0 = 45

Let x = 8

y = 45 + 65*8 = 565

The range is

45 < y < 565

Answer 2

Answer:

45 < y < 565

Step-by-step explanation:

y = 45 + 65x  where x is the number of hours

We want the range or the values that y can take

The plumber can work 0 to 8 hours

Let x = 0

y = 45+0 = 45

Let x = 8

y = 45 + 65*8 = 565

The range is

45 < y < 565
