I believe it’s 86
Since it tells you the measurements of two arcs that are opposite of one another you just add them together and divide it by two since the arcs correspond with the angle you’re looking for 86 is your answer
f(g(x)) means to plug the value of g(x) into every x you see in f(x) and do the math.
g(x) = 3x
f(3x) = 2(3x) - 1
f(3x) = 6x - 1
So, f(g(x)) = 6x - 1.
Understand?
h(f(x)) means to plug the value of f(x) into every x you see in h(x) and do the math.
h(x) = x^2 + 1
h(2x - 1) = (2x - 1)^2 + 1
h(2x - 1) = (2x - 1)(2x - 1) + 1
h(2x - 1) = 4x^2 - 4x + 1 + 1
h(2x - 1) = 4x^2 - 4x + 2
So, h(f(x)) = 4x^2 - 4x + 2

This is called COMPOSITION OF FUNCTIONS.
Answer:
(x) = x + 8
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 9(x - 8) ← divide both sides by 9
= x - 8 ( add 8 to both sides )
+ 8 = x
Change y back into terms of x with x = (x) , thus
(x) = x + 8
CATERING TOTAL COST F(X) = 10X + 300
TOTAL REQUIRED 14X
10X + 300 = 14X
10X - 14X = -300
-4X = -300
4X = 300
X= 300/4
X=75 <------------------SOLUTION
Answer:
The answer would be 3.
Step-by-step explanation:
-2x= -6-x+3 First you would add the x to each side. Then you are left with..
-x= -6+3 Now add 3 to -6
-x= -3 Now to get rid of the negative sign on the x, divide each side by -1.
x=3 That would be your final answer.
To Check Your Work, plug in 3 to the two x in the original equation, and see if you will get a true statement.
-2x=-6-x+3
-2(3)= -6-3+3 The threes would cancel out because -3+3=0
-6 = -6 This is a true statement so that means x=3 is the correct answer
