I believe the answer is D.
No, it is not a proportional relationship because the graph does not go through the origin.
Add the ratio to get total shares: 4 +1 = 5
Divide the total amount to share by the total shares:
150 / 5 = 30
Now multiply each set of shares by that:
4 x 30 = 120
1 x 30 = 30
120-30 = 90 more
Answer:
The athlete will run 200 kilometers.
A atleta percorrerá 200 quilômetros no total.
Step-by-step explanation:
She will run x kilometers.
She has already run 5/8 of the distance(5/8 of x), and still needs to run 75 kilometers.
So
The athlete will run 200 kilometers.
A atleta percorrerá 200 quilômetros no total.
The average rate of change formula is
f(b) - f(a)
arc = ----------------
b-a
Here, a= -10 and b = 10
(10)^2 + 9(10) + 18 - [ (-10)^2 + 9(-10) + 18]
Here arc = --------------------------------------------------------------
10 - (-10)
10^2 and -(-10)^2 cancel. 18 - 18 cancel.
90 - (-90) 180
This leaves us with arc = ----------------- = ------------- = 9 (answer)
20 20
