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

Any negative or positive number inside an absolute value will always come out positive.
The meaning of the question is
Let the unknown number be x
Therefore x+7=16-2x
Now 2x+x=16-7
3x=9
X=9/3
x=3

Step-by-step explanation:
Determine two points by substituting values for x and solving for y. Then plot the points and draw a dashed straight line through the points to indicate that they are not part of the inequality. Shade in the area above the line.
