...I'm really bad with word problems:
Tickets for a homecoming dance cost $20 for a single person or $35 for a couple. Ticket sales for the dance totaled $2280. If 128 peple attended the dabce, how many single tickets were sold?
let x = number of singles
y = number of couples
20x + 35y = 2280
x + 2y = 128
solve the system
Describe the transformation to the parent function y=f(x): y=f( x-2 )+1.
(What happens to the graph of y=f(x) to create the graph of y=f(x-2)+1?)
f(x-2) is f(x) translated to the right two units
f(x) + 1 is f(x) translated up one unit
put 'em together
