Answer:
I believe it would be 4x-8=-3x+13
Lets x = the number of songs
The product of the number of songs and $0.99 = 0.99 times x = 0.99x
The product of the number of songs and $0.99 is $7.92:
=
0.99x = 7.92
Hope that helps.
1. Out of a study of 64 dentists, 56 recommended.
2. 3 is the answer. Hope you do well on your test :)))
The rate of change is simply the derivative of a function with respect to the other variable. In this case the rate of change with respect to x is desired. Therefore
f(x) = x^3 - 3x^2
f'(x) = 3x^2 - 6x
therefore the rate of change of y with respect to x is dy/dx = 3x^2 - 6x
Answer:
-3
Step-by-step explanation:
f(x)=2x+1
f(-2)=2(-2)+1=-4+1=-3
