Answer:
The answer is A.
Step-by-step explanation:
Lets call f(x)=y, so y= 4*(3*x-5), we want to find 'x', using 'y' as a the variable.
Now lets change the name of 'y' to 'x', and 'x' to f^-1(x).
f-1(x) = (x+20)/12

Answer: x = 4</h3>
===============================================
Explanation:
Saying "Points A,B, and C are collinear" means the three points all fall on the same line. For the sake of simplicity, assume the line is horizontal.
Since B is between A and C, we know that the order of the points from left to right is A, B, C.
Through the segment addition postulate, we say,
AB+BC = AC
(x+3) + (x) = 11
x+3+x = 11
2x+3 = 11
2x = 11-3
2x = 8
x = 8/2
x = 4
------------------
Extra info:
Using x = 4, we see that
AB = x+3
AB = 4+3
AB = 7
Note how this adds to BC = x = 4, getting us,
AB+BC = 7+4 = 11
which is the length of segment AC. This confirms AB+BC = AC is true and confirms our answer.

Answer:
(5, 3 2/3)
Step-by-step explanation:
The centroid coordinates are the average of the vertex coordinates.
(A+B+C)/3 = ((2, 3) +(8, 1) +(5, 7))/3 = (2+8+5, 3+1+7)/3 = (15, 11)/3
The centroid is (5, 3 2/3).
_____
The graph shows the intersection of the medians. It is the centroid, (5, 3 2/3), as we calculated.
