Answer:
Step-by-step explanation:
By definition, according to this cross-section model, point is the segment bisector of all segments, according to which segments they are in congruence with. Anyway, here is how it is done:
3x - 8 = x + 4
-3x - 3x
_____________
−8 = −2x + 4
-4 - 4
_____________
−12 = −2x
____ ____
−2 −2
[Plug this back into all expressions above to get the measurements of
,
,
]
* Since point the segment bisector, you set the given equations equal to each other, then in the end, plug the x-value back into all expressions to get the length of
.

Let's assume the opposite is the case. So let's assume that a = b is true. If so, then f(a) and f(b) would be the same output. This is because we can replace 'b' with 'a', or vice versa. In other words, f(a) = f(b) would be true. But this contradicts the original inequality that f(b) < f(a)
So that is why 'a' cannot equal b. We don't know if a > b or if a < b (unless we are told if the function is strictly decreasing or increasing on the interval from x = a to x = b), so we just leave it as
Answer:
Step-by-step explanation:
Given :
Two points are given in graph (-6, -4) and {7, 5).
The point-slope form of the equation of a straight line is:
------------(1)
Let and
The slope of the line
Put all known value in above equation.
The slope of the line
We know m, and also know that , so we put these value in equation 1.
Therefore, the equation of the line is .
