12 less than the amount y divided by 2 is (Y/2)-12
Answer: See explanation
Step-by-step explanation:
Since Veronica buys 2 games for $30.00 each and a game controller for $19.59. The total cost to be paid will be:
= (2 × $30.00) + $19.59
= $60.00 + $19.59
= $79.59
Since Veronica lives in San Jose, California, where sales tax is 9.25%, the sales tax will be:
= 9.25% × $79.59
= 0.0925 × $79.59
= $7.36
Total amount paid = $79.59 + $7.36 = $86.95

Answer:
Tn = -n^2 - n + 21 is the formula for the nth term.
Step-by-step explanation:
The second differences are all equal in this quadratic sequence.
Now, the quadratic sequence has a formula of Tn = an^2 + bn + c
Find the value of a in an^2 by dividing the difference by 2:
-2/2 = -1
a = -1
Since T1 is 19 and T2 is 15 we can put that into the equation and simplify:
b + c = 20
2b + c = 19
Thus, b = -1 , c = 19 and the general formula for the nth term is Tn = -n^2 - n + 21
