Answer: A. All real numbers
Step-by-step explanation:
Find fg;
f(x) * g(x) = (x + 2) * ( 1 / x + 2)
= ( x + 2) / (x + 2)
= 1
In giving 1 as the product, the domain of fg is any real number.
Answer:
Step-by-step explanation:
Let the students price = x
Let the teacher's price = y
34x + 3y = 635
34y = 299.54
y = 299.54 / 34
y = 8.81
The only way to do this is to assume that students and teachers are charged the same amount for admission. But the question should say so.
So x = y
37x = 635.66
x = 635.66 / 37
x = 17.18
So the total spent per student was
8.81 + 17.18 = 25.99
It would be doubled i think actually no just do the same equation with 4. i need to see the question first

Answer:
b = (a - 6)/V
Step-by-step explanation:
a = Vb + 6
Subtract 6 from both sides:
a - 6 = Vb
b = (a - 6)/V
