Twelve men take 6 hours to finish a piece of work. After the 12 men have worked for 1 hour, the contractor decides to call in 8
Anna71 [15]
Twelve men take 6 hours to finish a piece of work.
In 1 hour, the 12 men will finish 1/6 of the work
( 1 job ) / ( 6 hrs ) = ( 1/6 of a job ) / ( 1 hr )
-----------------------------------------
That means there is of the job
left to do.
-------------------
If 12 men take 6 hours to finish a piece of work,
1 man will take 12 times as long, to finish the work, so
( 1 job ) / ( 6*12 = 72 hrs ) = rate of working for 1 man, or

-------------------
After 1 hour, there are a total of men working
20 men will work 20 times as fast as 1 man on the
of a job that remains, so
Let = hours for the 20 men to finish the job

6x² - 4y - 3x + 6x² + 8x = 12x² + 5x - 4y

Regroup terms on left

6x² + 6x² - 3x + 8x - 4y = 12x² + 5x - 4y

Write an equation for the line (4,7) and ( 1,1)2. Write an equation for the graph
Nastasia [14]

ANSWER:

y=2x-1

STEP-BY-STEP EXPLANATION:

We have that the equation in its slope-intercept form is the following:

\begin{gathered} y=mx+b \\ m\text{ is the slope and b is the y-intercept } \end{gathered}

The slope can be calculated as follows:

m=\frac{y_2-y_1}{x_2-x_1}

We use the points (4,7) and (1,1) to calculate the slope:

m=\frac{1-7}{1-4}=\frac{-6}{-3}=2

Now, we calculate the value of b, using the point (1,1) and the slope, like this:

\begin{gathered} 1=1\cdot2+b \\ b=-2+1 \\ b=-1 \end{gathered}

Therefore, the equation would be:

y=2x-1
