Find an equation of the line that passes through (3,4) and parallel to 4x-2y=5
Alex73 [517]
       4x - 2y = 5
4x - 4x - 2y = -4x + 5
             -2y = -4x + 5
              -2         -2
                y = 2x - 2¹/₂

          y - y₁ = m(x - x₁)
           y - 4 = 2(x - 3)
           y - 4 = 2(x) - 2(3)
           y - 4 = 2x - 6
             + 4        + 4
                y = 2x - 2

The number of hours required to do a job varies inversely as the number of people working. It takes 8 hours for 4 people to pain
dezoksy [38]

Answer: it will take 5 people 6.4 hours to do the work.

Step-by-step explanation:

The number of hours required to do a job varies inversely as the number of people working. Let h represent the number of hours required to do the job. Let p represent the number of people working. Therefore,

h is inversely proportional to p

Introducing a constant of variation, k, it means that

h = k/p

It takes 8 hours for 4 people to paint the inside of a house. Therefore

8 = k/4

k = 8×4 = 32

The formula becomes

h = 32/p

To determine how many hours it will take 5 people to do the work, we will substitute p = 5 into the formula. It becomes

h = 32/5 = 6.4 hours
