Answer:
B. 17
Step-by-step explanation:
The average rate of change is:
m_avg = (y₂ − y₁) / (x₂ − x₁)
m_avg = (100 − 49) / (10 − 7)
m_avg = 17
Answer:

General Formulas and Concepts:
<u>Algebra I</u>
- Range is the set of y-values that are outputted by function f(x)
Step-by-step explanation:
According to the graph, our line's y-values span from 2 to 14. Since both 2 and 14 are open dot, they are exclusive from the range:
Interval Notation: (2, 14)
Inequality Notation: 2 < y < 14

Answer:
below sea level.
Step-by-step explanation:
We have been given that a submarine hovers at 66 and 2/3 yards below sea level. This means that the position of submarine is negative.
We can represent this information as:
We have been also given that the submarine ascends 24 and 1/8 yards. This means we need to add to .
The submarine descends again 78 and 3/4 yards. This means we need to subtract from .
Therefore, the submarine's new position is below sea level.
