Who is Robert Recrde!!!
What does a linear function look like in its simplest
Y=mx+b
you download 2 dvds and 10 songs for $18. Your friend downloaded 3 dvds and 15 songs for $27. write a system of equations that represent this situation. can you determine the price of each dvd and each song?
2x+10y=18
3x+15y=27
0=0
the anwser is that you are unable to determine the price of one song and one dvd.

Carmen is creating beaded jewerly to give to her family and friends. For her family she assembled 1 bracelet and 2 necklaces, using total of 179 beads. for her friends, she assembled 1 bracelet and 4 necklaces, using a total of 321 beads. assuming she uses a consist number of beads. how many beads is she using for each? x for bracelets; y for necklaces.
x+2y=179
x+4y=321
x=37;y=71
