Amount of the job done after 2 hours:

2(1/6 + 1/8)

2(4/24 + 3/24)

2(7/24)

7/12 (amount of job finished)

.

amount of job left to do:

1 - 7/12

 

12/12 - 7/12

5/12 (remaining)

.

Let x = time (hours) slower press takes to finish job

then

x(1/6) = 5/12

multiplying both sides by 6:

x = 5/12 *6

x = 5/2 hours

or

x = 2 hours and 30 minutes

The slower press (8-hour press), will take h 3 hours, 20 minutes to complete the job

What is the simplified form of x plus 1 over x squared plus x minus 6 divided by x squared plus 5x plus 4 over x plus 4 ?
Lunna [17]
  x +1                 x^2 +5x +4              x +1                 (x +1)(x +4) 
---------------- / ---------------------- = ----------------- / ----------------------- = 
x^2 +x -6             x +4                    (x +3)(x -2)               x +4

       x +1                  1                     1
= ---------------- * ----------- = ------------------
    (x +3)(x -2)     ( x +1)       (x +3)(x -2)

so the second choice is right sure

What are the domain and range of the function?
Naily [24]

Answer: Domain: (-inf,inf) Range; [-4,inf)

Step-by-step explanation: Domain is x values possible and range is y values possible. Quadratics always have a domain of (-inf,inf) and the range starts from -4 going up infinitely. and if -4 is included then we use a bracket therefore,  [-4,inf). Also, infinity always has a parenthesis.
