What is the 12th term of the arithmetic sequence given by the explicit rule a(n)= -39 + (n - 1)(7)?

38

Step-by-step explanation:

Substitute n = 12 into the explicit rule

a(12) = - 39 + (12 - 1)7 = - 39 + (11 × 7) = - 39 + 77 = 38

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
