Answer:

3x-12=y

which equals to

1/y=1/(3x-12)

Now,multiply both sides by x

x/y=x/(3x-12)

8x/2y=4x/y=4x/(3x-12)

Write the equation of the line that passes through the points (-9, -8) and (–6,6).
sveta [45]

Answer:

Slope - intercept form    y = \frac{14}{3} x  + 34

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given points are ( -9 ,-8 ) and (-6,6)

slope of given two points

    m = \frac{y_{2} -y_{1} }{x_{2}-x_{1}  } = \frac{6-(-8)}{-6-(-9)} = \frac{14}{3}

The equation of the straight line passing through the points and having slope

          y - y_{1} = m ( x - x_{1} )

        y - (-8) = \frac{14}{3}  ( x - (-9) )

          3 y + 2 4 = 14 x + 126

           3 y = 14 x + 126 - 24

          3 y = 14 x + 102

            y = \frac{14}{3} + \frac{102}{3}

           y = \frac{14}{3} x  + 34

Slope - intercept form  y= mx +C

Slope - intercept form    y = \frac{14}{3} x  + 34

Two grandparents want to pick up the mess that their granddaughter had made in her playroom. One can do it in 15 minutes working
Crank

Answer:

  6 2/3 minutes

Step-by-step explanation:

Their rates in "jobs per hour" are ...

  (60 min/h)/(15 min/job) = 4 jobs/h

and

  (60 min/h)/(12 min/job) = 5 jobs/h

So, their combined rate is ...

  (4 jobs/h) + (5 jobs/h) = 9 jobs/h

The time required (in minutes) is ...

  (60 min/h)/(9 jobs/h) = (60/9) min = 6 2/3 min

Working together, it will take them 6 2/3 minutes.
