Answer: 55x + 75 = 350; 5 hours

Step-by-step explanation:

What we know:

- A flat fee is $75

- John charges $55 an hour

- The total charge is $350

We need to write an equation to find how many hours John works.

<em>x </em>will represent hours worked.

55x + 75 = 350

We now need to solve for x.

Subtract 75 from both sides.

55x + 75 - 75 = 350 - 75

Simplify.

55x = 275

Divide 55 from both sides.

55x/55 = 275/55

Simplify.

x = 5

John worked 5 hours.

To check our work, we just plug in our x value!

55(5) + 75

275 + 75 = 350

What polynomial has roots of −5, −4, and 1?
katrin [286]

Answer:

The last choice.

Step-by-step explanation:

The  last term is  - 20 and because we have a coefficient of 1 on the x^3,  and in order to get this last term  and the given roots the factors have to be

(x  + 5)(x + 4)(x - 1)  so it is the last option.
