Y = 2x/x-7
x = 2y/y-7
xy - 7x = 2y
-7x = 2y - xy
-7x = y(2-x)
y = -7x / 2-x
y = 7x / x-2
f-¹(x) = 7x / x-2
Answer:

Step-by-step explanation:
the minimum of f is for x = 1 and f(1)=0
f is decreasing for x<=1 and increasing for x>=1
so the domain is 

x>=1 so x is positive and we can take the square root
so 
Hello,
Using the theorem of Thalès,
PR/TP=QS/TQ==>QS=4*20/16=5
Answer A
180 = 2x + 26
-26 -26
154 = 2x
÷2 ÷2
77 = x
One of the sides is 77
