Ahat [919]

m= -19/1

We need to use the slope equation

$\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

We are working with the points,

(17, 2) and (18, -17)

x1 y1 x2 y2

$\frac{-17-2}{18-17}$

Answer:

15). is done

16).

$slope = \frac{ {y}^{1} - {y}^{o} }{ {x}^{1} - {x}^{o} } \\ = \frac{2 - ( - 2)}{ - 3 - 9} \\ = \frac{4}{ - 12} \\ slope = - \frac{1}{3}$

A piece of work can be completed by 45 men in 90 days if only 30 men are available, how many days will it take to complete the s

andrew-mc [135]

Answer:

135 days

Step-by-step explanation:

Often, we measure work in man·days. This piece of work requires ...

(45 man)·(90 days) = 4050 man·days

When there are only 30 men, the number of days required can be found by dividing this work by the number of men:

4050 man·days/(30 man) = 135 days

_____

Another approach is to realize the time is inversely proportional to the number of men. If the number of men is 30/45 = 2/3 the original, then the time will be 3/2 the original, or ...

(3/2)·90 days = 135 days.
