ANSWER:

It would take them about 3 hours to paint the room together.

EXPLANATION:

The least common denominator of 7 and 5 would be 35, so if we set 7x+5x equal to 35, the answer rounds up to 3. (or 2.9 if rounded to the nearest tenth.)

At which values of x does the function F(X) have a vertical asymptote? F(X) =3/x(x-5)(x+1)
damaskus [11]

Answer:

There are vertical asymptotes at x:  {-1, 0, 5}

Step-by-step explanation:

It's easier (at least for some) if you write this function as

                  3

F(X) = ------------------

            x(x-5)(x+1)

Can you now see that if x = 0, this function is undefined?  Same for x = 5 and x = -1?  There are vertical asymptotes at x:  {-1, 0, 5}

Work in the five days?
Ghella [55]

Answer:

9.3

Step-by-step explanation:

last week she worked 45.6 hours. since 40 hours is the limit for normal working hours, she worked 45.6-40 = 5.6 hours overtime.

this week she worked 9.7+8.3+8+9.1+8.6 hours = 43.7 hours.

she worked therefore 43.7-40 = 3.7 hours overtime.

so, in total of the two weeks, she worked 5.6+3.7 = 9.3 hours overtime.
