Answer:
the graph will describe 13x+15 if the cost per audio book goes up by $1.00.
Step-by-step explanation:
This happens because the coefficient to x is 12 before the change. If the change is the cost per audio book going up by one dollar, the coefficient changes to 13. The initial joining fee is the same ($15.00).
Answer:4
Step-by-step explanation:
2+2 = 4
Adding 2 in 2 gives us 4.
You know when it is a periodic function if the values repeats in regular intervals or periods. An example of this is trigonometric functions that repeat over intervals of 2 pi radians.
20% * 300 = 2 * (10% * 300) = 2*30 = 60
These matrices ARE inverses of each other!
