Fred takes 3 hours to dig a garden. It takes Jason 5 hours to

Irina18 [472]

It takes them 1 7/8 hrs to complete the job together.

How:
Fred = 3 hrs
Jason = 5 hrs

1/3x + 1/5x = 1/x

3x x 5x = 15 —> 3x/15 + 5x/15 = 15/15

3x + 5x = 8x —> 8x/15 = 1.875 = 1 7/8 hrs

Write an equation of the line that passes through a pair of points:

vredina [299]

Answer:

The equation of the line that passes through a pair of points

$y = \frac{-1}{8} ( x ) -\frac{11}{8}$

Step-by-step explanation:

Explanation:-

Given points are ( 5 ,-2) and ( 3,-1)

slope of the line

$m = \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{-1-(-2)}{-3-(5)} = \frac{1}{-8}$

The equation of the line that passes through a pair of points

$y - y_{1} = m ( x - x_{1} )$

$y - (-2) = \frac{-1}{8} ( x - (5) )$

$y = \frac{-1}{8} ( x ) +\frac{5}{8} -2$

$y = \frac{-1}{8} ( x ) +\frac{5-16}{8}$

$y = \frac{-1}{8} ( x ) -\frac{11}{8}$
