3) x = 2y

semsee45

Answer:

1.  y = x - 4

2. y = x + 6

3. y = (1/2)x

4. c = 1.55n

5. e = 7.75h

 25 hours

Step-by-step explanation:

1.  y = x - 4

2. y = x + 6

3. slope m = change in y ÷ change in x

⇒ m = (7 - 6) ÷ (14 - 12) = 1/2

⇒ y - 6 = 1/2(x - 12)

⇒ y = (1/2)x

4. let c = cost

   let n = number of songs

Ordered pairs:  (1, 1.55) (2, 3.10) (5, 7.75)

⇒ c = 1.55n

5. let h = hours worked

  let e = total earnings

earns $7.75 per hours

⇒ e = 7.75h

video game system = $193.75

⇒ 193.75 = 7.75h

⇒ h = 25
