Let x be the number of texts (amount of texts) Carly does in a month.
Let y be the "total" amount Carly will have to pay in a month.
Then, as per the TURKEY plan, Carly's monthly total cost will be represented by the equation as shown:
As we can clearly see in the above equation even if Carly does not text a single message (when x=0), even then they will have to pay $20 for that month.
For the GOBBLE plan, the equation will be: .
In this plan as there is no fixed charge, Carly wont have to pay anything extra if they dont make a call.
Answer:
A rational expression that has the nonpermissible values and is .
Step-by-step explanation:
A rational expression has a nonpermissible value when for a given value of , the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:
(1)
Then, the factorized form of must be:
(2)
If we know that , then the rational expression is:
(3)
A rational expression that has the nonpermissible values and is .

Answer:
Step-by-step explanation:
Given voltage of primary coil is
And voltage of secondary coil is
A transformer is a device that contains primary and secondary coil. These coils are mounted on soft iron. The change in voltage depends upon the number of turns of primary coil and secondary coil .
Following equation represents the relation between them.
Then, ratio of the number of wire turns on the primary coil to the number of turns on the secondary coil is
180=(3x+25)+2x. Soooooo X=31
