Total cost = Price of juice + price of chocolate + tax = 10 + 10 + [(16/100) x 20]
= 20 + 3.2
= $23.2

Answer:
The answer is (g°f)(-1) = 27
Step-by-step explanation:
* (g°f)(1) ⇒ means make the domain of g is the range of f
- At first find the value of f(-1)
- Take the answer and substitute it as the value of x for g
- So the range of f is the domain of g
∵ f(x) = 4x + 7
∵ The domain of f = -1 ⇒ x is the domain
∴ f(-1) = 4(-1) + 7 = -4 + 7 = 3 ⇒ f(-1) is the range
∵ g(x) = x³
∵ x = f(-1) = 3 ⇒ the domain of g
∴ g(3) = 3³ = 27 ⇒ the range of g
* (g°f)(-1) = 27
8/3 is your simplified answer
Answer: B
Step-by-step explanation:
y = mx + mc
The perpendicular will have slope -1/m and intercept mc, which is
y = (-1/m)x + mc
For the answers you have to factor out a -1/m from both terms:
