You go to a school dance. there is an entrance fee, and there are slices of pizza for sale. after having 1 slice of pizza, you have spent a total of $6. after having 2 more slices of pizza, you have spent a total of $10. write an equation that represents the total cost y after buying x slices of pizza at the dance
divide the top and bottom by 3
99/3 = 33
15/3 = 5
-99/15 = -33/5
-11(1 + 3k).
-11 - 33k
the common factor is - 11.
so we divide - 11 - 33k to get the other factor.
the factors are -11(1 + 3k).
the formula for nth term of a the sequence is given as
finding the 10th term means finding , which means to plug in 10 into n, in the nth term formula.
