The interval at which the average rate of change of f(x) is negative is from x = 0 to x = 2.5.
<h3>What is the average rate of change?</h3>
The average rate of change is a type of function that describes the average rate at which a quanity <u>decreases or increases</u> with respect to another quanity.
Generally, for a function with a negative average rate of change, the graph must face down and have a negative slope.
Based on the graph shown in the image attached below, we can deduce that the interval for which the average rate of change of f(x) is negative is from x = 0 to x = 2.5.

Answer:
x = 50
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
The given angles are exterior angles of the polygon, thus
2x + 2x + x + 40 + x + 20 = 360, that is
6x + 60 = 360 ( subtract 60 from both sides )
6x = 300 ( divide both sides by 6 )
x = 50
Answer:
That is called an 'irrational algebraic number'

Answer:
D. 30
Step-by-step explanation:
60 = 2x
30 = x
Answer:
Step-by-step explanation:
- Firstly, plug in the point and slope into the slope-intercept equation format:
When lines are parallel to one another, their slopes are the same. But they have different y-intercepts. To explain further, slope is the angle of measure of a line from a horizontal standpoint and knowing that parallel angles must have the same angle, it can be concluded that parallel lines would have the same slope or in other words, an equal slope.
Now solving, use algebraic concepts:
11 = -8(-1) +b (Now solve for b)
11 = 8 + b (Subtract 8 from both sides) (Use the "Right" to "Left")
-8 -8
3 = b (Switch terms)
b = 3
Now let's write the equation with only slope and y-intercept.
Getting the result of:
y = -8x + 3
