Solution:
We have:
f(x) = √x
g(x) = 7x + b
y = f(g(x)), Given point on the graph (x, y) = (4, 6)
Use: f(x) = √x
f(g(x)) = √(g(x))
y = √(7x + b), x = 4, y = 6
6 = √(7(4) + b)
6² = (7(4) + b)
36 = 28 + b
36 - 28 = b
8 = b
b = 8
Answer: an adult ticket cost $8 and a student ticket cost $4
Step-by-step explanation:
Let x represent the cost of one student ticket.
Let y represent the cost of one adult ticket.
A drama club earns $1040 from a production. It sells a total of 64 adult tickets and 132 student tickets. It means that
132x + 64y = 1040 - - - - - - - - - -1
An adult ticket costs twice as much as a student ticket. It means that
y = 2x
Substituting y = 2x into equation 1, it becomes
132x + 64 × 2x = 1040
132x + 128x = 1040
260x = 1040
x = 1040/260 = 4
y = 2x = 2 × 4
y = 8
Answer:
50000. easy
Step-by-step explanation:
We are given the following coordinates:
(0,6), (π/2, 7); (π, 8); (3π/2, 7); and (2π, 6)
If we graph these points, we will observe that the function is a cosine function. Since the function does not pass through the origin. Instead, it has a y-intercept equal to 6. <span />
You can not call it domain cause it is only an expression not equation
you have to exclude 0 from domain
