Answer:

  2 2/35 hours

Step-by-step explanation:

In 1 hour, the total amount of the house that is painted is ...

  1/8 + 1/4 + 1/9 = 35/72 . . . of a house

We need to multiply the time (1 hour) by 72/35 to find the number of hours required for one entire house:

  72/35(1 h) = 2 2/35 h

It would take them 2 2/35 hours to paint the house working together.

Graph the line for <br> y+1=−3/5(x−4)<br> on the coordinate plane.
Naddika [18.5K]
Please enclose that -3/5 in parentheses:  <span>y+1= (−3/5)(x−4)
</span>
Let's use the intercept method to graph this line.
First, set x = 0 and find y; this y will be the y-coordinate of the vertical intercept:

y+1= (−3/5)(0−4)  =>  y = -1 + 12/5 = -5/5 + 12/5 = 7/5.  Plot (0, 7/5).

Next, set y = 0 and find x; this will give us the coordinate of the horiz. int.:

0+1= (−3/5)(x−4) => -5/3 = x - 4, or x = 4- 5/3, or  x = 7/3.  Plot (7/3, 0).

Now draw a straight line thru these two points.
