Answer:
Step-by-step explanation:
Reasoning A store sells packages of comic books with a poster. A poster and 5 comics cost $13.99. A poster and 12 comics cost $20.99. Write a linear function rule that models the cost y of a package containing any number x of comic books. Suppose another store sells a similar package, modeled by a linear function rule with initial value $. Use pencil and paper. Explain which store has the better deal. The linear function rule is y nothing.
Answer:
y=-2(x+2)
Step-by-step explanation:
plug in(-2,0) into y-y1=m(x-x1)
y=m(x+2)
slope =m=-2
y=-2(x+2)
84= 7(6+a)
84= 42 +7a
84-42= 42-42 +7a
42= 7a
42/7= 7a/7
6= a
-84= -6( p+6)
-84= -6p -36
-84+36= -6p -36+36
-48= -6p
-48/-6= -6p/-6
8 =p
Answer:
AM = 900
CI = 500
I have to be honest, this is the most ridiculously worded question of this type that I have ever seen... ask you teacher, why it was so important to force you to solve it using only one variable?
Step-by-step explanation:
(AM) + (1400-AM) = 1400
2(AM) + 3(1400 - AM) = 3300
2AM + 4200 -3AM = 3300
-AM = -900
AM = 900
CI = 500
