Answer:
C
Step-by-step explanation:
C is not a function because 5 has two y values
Answer:
f(x) = g(x-9)
Step-by-step explanation:
Top:
x / (x + 1) - 1 / x
= [x^2 - (x +1)] / x(x+1)
= (x^2 - x - 1 ) / x (x+1)
Bottom:
x / (x + 1) + 1 / x
= [x^2 + (x +1)] / x(x+1)
= (x^2 + x + 1 ) / x (x+1)
Now you have:
(x^2 - x - 1 ) / x (x+1)
----------------------------
(x^2 + x + 1 ) / x (x+1)
= (x^2 - x - 1 ) / x (x+1) * x (x+1) / (x^2 + x + 1 )
= (x^2 - x - 1 ) /(x^2 + x + 1 )
Answer:
x^2 - x - 1
---------------------
x^2 + x + 1
Answer:
Function- a relationship or expression involving one or more variables.
A domain refers to the set of possible input values.
The range is the set of possible output values.
Step-by-step explanation:
Answer:
∠S = 21.10°
∠M = 79.45°
PM = 9.16
Step-by-step explanation:
Here Pythagorean theorem and trigonometry suffice to solve our problem.
From the Pythagorean theorem we get:
and
We solve for 
in the second equation and get:
Now since
Therefore
and
And finally again from the Pythagorean theorem:
Thus,
∠S = 21.10°
∠M = 79.45°
PM = 9.16.
