Answer:

AB = BC = AC = 15

Step-by-step explanation:

Since the triangle is equilateral then the 3 sides are congruent.

Equate any 2 sides and solve for x , that is

AC = AB , so

11x - 7 = 6x + 3 ( subtract 6x from both sides )

5x - 7 = 3 ( add 7 to both sides )

5x = 10 ( divide both sides by 5 )

x = 2

Then

AC = 11x - 7 = 11(2) - 7 = 22 - 7 = 15 , thus

AB = BC = AC = 15

Determine whether f(x) = 5x+1/x and g(x)= x/ 5x+1 are inverse functions explain how you know. please explain in steps or worded
Len [333]

Hello from MrBillDoesMath!

Answer:

No


Discussion:

If the functions are inverses, then f(g(x)) = x  for appropriate x. Consider x = 1.

g(1) = 1/ (5(1) + 1) = 1/6

f(g(1)) = f (1/6) =  5(1/6) + 1/ (1/6) = 5/6 + 6 = 6 5/6   <> 1

Conclusion: f(g(1)) <> 1 so the functions are not inverses


Thank you,

MrB

Line BD is tangent to circle O at C, Arch AEC = 299, and ACE = 93. Find Angle DCE.
VladimirAG [237]
In triangle ACE,
we know C=93,E can be calulated by using arch angle AEC...what ever that is....,using this we get  A=180-(E+93)

So, by alternate segment theorem, DCE= A.

thats all i can say.
