Answer:
Therefore, Steve will paint house for 20.6 days.
Step-by-step explanation:
We know that Steve determines that it would take them 9 days to paint the house together (if they were both healthy) and that it would take Janet (when healthy) 16 days to paint the house alone.
We conclude that in 1 day Janet painted 1/16 of the house. In nine days, Janet painted 9/16 of house.
So, 7/16 of house paint Steve in nine days.
We have the following proportion:
Therefore, Steve will paint house for 20.6 days.
<h3>Given</h3>
A = 2k² -k -15
L = k² -9
<h3>Find</h3>A/L
<h3>Solution</h3>See in the explanation
<h2>Explanation:</h2>In this exercise, <em>we have the following points:</em>
And <em>the following linear equations:</em>
When plotting these graphs, we find the following facts:
<h3>For (1):</h3>We see the graph in the first figure below. The graph only passes through the point (0, 8)
<h3>For (2):</h3>This is the second graph below. The graph passes neither through point (0, 8) nor (6, 4)
<h3>For (3):</h3>This is the third graph below. The graph passes neither through point (0, 8) nor (6, 4)
<h3>For (4):</h3>This is the fourth graph below. The graph only passes through the point (0, 8)
So, <em>there is no any equation of the line that passes through the points (0.8) and (6.4) at the same time.</em>
