Answer:
Perpendicular lines are lines that intersect at right angles. If you multiply the slopes of two perpendicular lines in the plane, you get −1 . That is, the slopes of perpendicular lines are opposite reciprocals .
Hope this help:)
Because u have to multiply by ten first
Answer:
y/2
Step-by-step explanation:
Considering the given functions in the graph, we have that:
<h3>How to find (f + g)(3) looking at the graph?</h3>
We look at the graph, and find f(3) and g(3), then add them. Hence:
Then the addition is:
(f + g)(3) = f(3) + g(3) = 0 + 4 = 4.
<h3>As for (f - g)(1):</h3>
Same logic, at the graph we have that:
Hence:
(f - g)(1) = f(1) - g(1) = -1 - 1 = -2.
