represents the value in dollars of a vehicle x years after it has been purchased
new.
What is the average rate of change in value per year between years 5 and 10?

the answer is d

step-by-step explanation:

f(x)=2/3x-8, which give g(x) the greatest value.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
