Answer:SOLUTION
The midpoint for two points P=(px,py) and Q=(qx,qy) is M=(px+qx2,py+qy2).
We have that px=1, py=3, qx=5, qy=1.
Thus, M=(1+52,3+12)=(3,2).
ANSWER
M=(3,2)A
Step-by-step explanation:

First, replace the numerator with the parentheses.
Second, multiply both sides by 3.
Third, multiply 2 × 3 to get 6.
Fourth, take away 15 from each side.
Fifth, simplify -6 - 15 to get -21.

Answer:
n = -21
Answer:

Step-by-step explanation:
The given function is
f(x) = 4x
As we know
f(x) = y, which implies x= 
Therefore,
y = 4x
x = 
as x= 
So,

replacing y by x in the above expression

So our inverse function is
