Answer:
DVD: $16
CD: $11
Step-by-step explanation:
These two linear equations can represent the system of equations where x equals the cost of a DVD and y equals the cost of a CD:
3x+4y=92
2x+3y=65
When graphed, the solution is at (16,11).
Therefore, one DVD costs $16 and one CD costs $11.

Answer:
1/12 (i think) or 0.083
Step-by-step explanation:
well she buys you 1 and there is 12 so it would be 1 out of 12 which is written as 1/12
Answer:
4/3
Step-by-step explanation:
Sounds as though this problem presented several rates of change, but you have shared only one: 3y - 4x = 3. If we take x to be the independent variable, then 3y = 4x + 3, and y = (4/3)x + 1. The rate of change of this function (the rate of change of y with respect to x) is therefore 4/3.
Answer:
x(3x+14)
Step-by-step explanation:
what do those terms share? they share the letter "x"
therefore we multiply x by 3x^2/x + 14x/x
3x^2/x = 3x and 14x/x = 14
