Using the together rate, it is found that it would take the assistant 31 hours and 30 minutes to do it alone.
<h3>What is the together rate?</h3>It is the sum of each separate rate.
In this problem, the rates are given as follows:
- Josephine: 1/9.
- Assistant: 1/x.
- Together: 1/7.
Hence:
2x = 63
x = 31.5.
It would take the assistant 31 hours and 30 minutes to do it alone.

Answer:
y = - x -
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
19x + 15y = - 6 ( subtract 19x from both sides )
15y = - 19x - 6 ( divide all terms by 15 )
y = - x -
, that is
y = - x -
← in slope- intercept form
