The answer is B. If you substitute the values of x, y and z in you get 1 * -10 which just is -10. -10 / 2 = -5.
As per the problem,
The larger pump takes 40 minutes to fill the pool.
The smaller one takes 60 minutes.
When both the pumps are working , let the time taken be x minutes , then we can write
Hence, when both the pumps works together, Time taken =24 minutes.
The slope of the line that passes through the pair of point (5, 7), (2, 1) is 2
<em><u>Solution:</u></em>
Given that line that passes through the pair of point (5, 7), (2, 1)
To find: slope of the line
<em><u>The slope of line is given as:</u></em>
For a line passing through two points and slope is given as:
Here in this problem,
<em><u>Substituting the values in above formula,</u></em>
Thus the slope of given line is 2
This is a way to work it out
