Step-by-step explanation:
the function is
ride cost c = mile rate r × miles m + flat rate f
c = r×m + f
now let's put the values in we know and solve for r and f :
9 = r×3 + f
17 = r×7 + f
now, since one term is the same in both equations, we use a simple trick for speed, and we subtract the whole first equation from the second :
17 = r×7 + f
- 9 = r×3 + f
-------------------
8 = r×4 + 0
r = 8/4 = $2
9 = 2×3 + f = 6 + f
f = $3
the first rate is $3, and it costs $2 per mile.
Answer:
It is incorrect because the following gives you a total of 171 and not 1.

Answer:
9s^3 + 13s
Step-by-step explanation:
Combine like terms and simplify.
(6s^3 + 3s^3) + (9s + 4s) + (10 - 10)
(9s^3) + (13s)
9s^3 + 13s
