It has been proven that of all line segments drawn from a given point not on it, the perpendicular line segment is the shortest.
<h3>How to prove a Line Segment?</h3>
We know that in a triangle if one angle is 90 degrees, then the other angles have to be acute.
Let us take a line l and from point P as shown in the attached file, that is, not on line l, draw two line segments PN and PM. Let PN be perpendicular to line l and PM is drawn at some other angle.
In ΔPNM, ∠N = 90°
∠P + ∠N + ∠M = 180° (Angle sum property of a triangle)
∠P + ∠M = 90°
Clearly, ∠M is an acute angle.
Thus; ∠M < ∠N
PN < PM (The side opposite to the smaller angle is smaller)
Similarly, by drawing different line segments from P to l, it can be proved that PN is smaller in comparison to all of them. Therefore, it can be observed that of all line segments drawn from a given point not on it, the perpendicular line segment is the shortest.

Answer: The answer is f(x) = -7x + 7.
Step-by-step explanation: We are give a relation as follows :

From here, we need to find the expression for f(x).
Here, we will be using the following properties of exponents :

We have

Thus, the required expression is f(x) = -7x + 7.
Answer:
The answer would be -7/20
Step-by-step explanation:
You have (7/15) * (-3/4)
What you have to do is multiply the numerators, 7 and -3, which is -21.
Then you multiply the denominators, 15 and 4, which is 60.
Your fraction should then look like this (-21/60). *numerator/denominator
Then you simplify them by divided both numbers by 3, which gives your answer, (-7/20).
Since 7 is prime, the fraction can no longer be simplified any more.

Let x be the unknown quantity. First, cross multiply to get 56x=392. Then divide both sides of the equation by 56 to get x=7.
