The average rate of change is defined as:
For AVR to be negative, it must comply with:
Therefore, we observe that the interval that fulfills these conditions is the whole interval to the right of the parabola.
Among the options given, this interval is:
1 to 2.5
Answer:
An interval on the x-axis that has a negative rate of change is:
D. 1 to 2.5
Answer:
(a)
Shortest Side of the trapezoid =6 yds
Longest Side =8 yds
(b)42 Square Yards
Step-by-step explanation:
<u>Part A</u>
In the Trapezoid, Width =6 yd
Since the shortest side of the playground and its width have the same dimension, then:
<u>Part B</u>
Area of the Playground
In the trapezoid
a=6 yd, b=8 yd, h=Width=6 yd
Area of a trapezoid<u />
<u /><u />
Answer:
Option D- y > x – 2 and y < x + 1
Step-by-step explanation:
To determine : Which system of linear inequalities is represented by the graph?
Solution : First we examine the graph
The shaded region in purple is drawn using two line
The first line above the origin passing through the points (0,1) and (-1,0)
The equation of line passing through two points is
So, the equation of that line
The second line below the origin passing through the points (0,-2) and (2,0)
The equation of line passing through two points is
So, the equation of that line
Now, to check the system of inequality substitute point (x,y)=(0,0)
First equation
means
Second equation
means
Therefore, Option D is correct.
The linear inequalities of the system is y > x-2 and y < x + 1
