Step-by-step explanation:
well you have to identify what the method is first.
He is basically pricing things by the count of 5. So, you can assume that it would cost $25.
Idk, this is a weird problem
A(x) = 3x + 1
b(x) = √(x-4)
Therefore

This composition of functions is only defined as a real number when x≥0.
Therefore its domain is x = [1,∞]
Answer: [1,∞]
-12+3b-1=-5-b
Combine like terms to get:
3b-13=-5-b
Add 13 to both sides:
3b= 8-b
Add b to both sides:
4b=8
Divide both sides by 4:
4b/4=8/4
b=2
Final answer
b=2
Answer:
3. b
2. c
Step-by-step explanation:
