Answer:
<em>The length of AB is 40</em>
Step-by-step explanation:
<u>The Midpoint of a Segment</u>
If A and B are the endpoints of a segment, and C is the midpoint of AB, then the distance from A to C is equal to the distance from B to C.
We are given the lengths BC=3x-7 and AC=9x-61:
9x - 61 = 3x - 7
Subtracting 3x:
6x - 61 = - 7
Adding 61:
6x = 54
Dividing by 6:
x = 9
The total length AB is
BC+AC=3x - 7 + 9x - 61 = 12x - 68
Substituting x=9:
AB = 12*9 - 68 = 40
The length of AB is 40
Answer:
Inverse function y =
+ ![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
Find the plots attached!
Step-by-step explanation:
Starting with our equation:
f(x) = -3x + 4 - 2 this is equal to y = -3x +2 (we can call f(x) as y)
To find the invert we swap x for y
y = -3x +2 become x = -3y +2 now we isolate y again!
x - 2 = -3y
= -y
y =
+
(the inverse function is also called ![f(x)^{-1}](https://tex.z-dn.net/?f=f%28x%29%5E%7B-1%7D)
I hope it helps :)
