Answer:
a. y = 7500 - 500x
b. $ 4,500
Step-by-step explanation:
a. Given,
The original value of the phone = $ 75,00
Let the linear function that shows the value of booth after x years,
y = b - ax,
For x = 0 years, y = 7500
⇒ 7500 = b - a(0) ⇒ b = 7500
For x = 15, y = 0,
0 = b - 15x ⇒ 0 = 7500 - 15a ⇒ 15a = 7500 ⇒ a = 500
Hence, the function that shows the value of car after x years,
y = 7500 - 500x
b. if x = 6,
The value of the booth after 6 years would be,
y = 7500 - 500(6) = 7500 - 3000 = $ 4,500
Answer:
y = 3x + 3
Step-by-step explanation:
when you check, only that equation delivers the correct x and y pairs.
x = 0, => y = 3×0 + 3 = 3
x = 1, y = 3×1 + 3 = 3+3 = 6
x = 2, y = 3×2 + 3 = 6 + 3 = 9
x = 3, y = 3×3 + 3 = 9 + 3 = 12
it all fits.
