F(x) = 50x
independent variable = x
dependent variable = f(x)
f(x) = 50x......find f(6)
f(6) = 50(6)
f(6) = 300
I think the answer is d. -11
Explanation:
Replace the variable x with 3 in the expression.
f(3)=-2•3-5
Multiply -2 by 3
f(3)=-6 -5
Subtract 5 from -6
f(3)= -11
Then the answer should be -11.
Step-by-step explanation:
1. Amplitude = 1. g(x) = 1 sin(6x). The coefficient 1 is the amplitude. The range of the function is
or, in interval notation, [-1, 1]
2. The period is
.
x-intercepts (at the beginning, middle, and end of the period) 
Maximum (1/4 of way through period) 
Minimum (3/4 of way through period) 
Answer:
56 music files
Step-by-step explanation:
From the above question:
Let the number of music files
Arely has = x
Valerie has = y
Arely has 4 fewer than twice as many music files as Valerie.
x = 2y - 4
They have a combined number of 86 music files.
x + y = 86
We substitute 2y - 4 for x in the above equation
2y - 4 + y = 86
3y - 4 = 86
3y = 86 + 4
3y = 90
Divide both sides by 3
3y/3 = 90/3
y = 30
Hence, Valerie has 30 music files.
The number of music files that Arely has is calculated as:
x = 2y - 4
x = 2(30) - 4
x = 60 - 4
x = 56
Arely has 56 music files
I am not Sydney, but I hope I can answer this question. We know that one sign equals 6 movies, so 18/6=3. B would be your answer.
