Answer:
1. X3, 15x - 10y = 80 15x - 7y = 51
-17y = 29
2. 8 = 1/60 + a. 8 - 1/60 = 7.98333333333
6 = 1/80 + b. 6 - 1/80 = 5.9875
13.9708333333

Answer:
y=x+5.99
Step-by-step explanation:
A poster and 2 comics cost $7.99
(2,7.99)
A poster and 11 comics cost $16.99.
(11,16.99)
Let y be the cost of package and x be the no. of comics
We will use two point slope form :
(x1,y1) = (2,7.99)
(x2,y2) = (11,16.99)
Formula :
y-y1 = y2-y1/x2-x1(x-x1)
Substitute the values:
Hence a linear function rule that models the cost y of a package containing any number x of comic books is y=x+5.99
Answer:
19) x=-3, 20) a=1, 21) b=3, 22) x=8
