Answer: 2.79 hours.
Step-by-step explanation:
Given that the function for the learning process is T(x) = 2 + 0.3 1 x , where T(x) is the time, in hours, required to produce the xth unit
To calculate the time for the new worker to produce 10 units, substitute 10 for x in the equation above.
T(x) = 2 + 0.31 (10)
T(x) = 2 + 3.1
T(x) = 5.1 hours
To calculate the time for the new worker to produce 19 units, substitute 19 for x in the equation above.
T(x) = 2 + 0.31(19)
T(x) = 2 + 5.89
T(x) = 7.89 hours
The time required for a new worker to produce units 10 through 19 will be
7.89 - 5.1 = 2.79 hours
Answer:

Step-by-step explanation:
Given:


The attachment completes the question
From the attachment, the slope of the line was calculated as:

This step is inaccurate because the slope of a line is calculated using

Which gives



The line equation is then calculated using:

Substitute values for m, x1 and y1


Open bracket

Make y the subject

Answer:
-3x - 7y
Step-by-step explanation:
x - (4x - 2y) - 5y
x - 4x - 2y - 5y
Combine like terms
x - 4x = -3x
-2y - 5y = -7y
Now, we have our final answer:
-3x - 7y
