Answer:
The graph in the attached figure N 2
Step-by-step explanation:
The complete question in the attached figure N 1
we have the ordered pairs
(-4,9),(-1,3),(0,1),(2,-3)
Using a graphing tool
Plot the given ordered pairs in the coordinate plane
Remember that
In a ordered pair (x,y), the first coordinate is the location of the point in the x-axis and the second coordinate is the location of the point in the y-axis
see the attached figure
The graph represent a line
<em>Find the equation of the line</em>
<em>Find the slope</em>
take two points

The equation of the line in slope intercept form is equal to

we have

substitute

Answer:
The number is -1
Step-by-step explanation:
The equation for the first part is (2n+7)2. This is because "twice a number" is 2n and "7 is added" will make it 2n+7. The "sum is multiplied by two" Is multiplying everything by two. This will make it (2n+7)
The second part is -8n+2. Since a number is multiplied by negative eight it will be -8n. Then it is added by two.
Both equation equal each other the overall equation will be (2n+7)2=-8n+2
You will distribute. making it 4n+14=-8n+2
Add 8n to both sides making it 12n+14=2
subtract 14 from both sides making it 12n=-12
Divide both sides by 12 . making it number=-1
Formula for circumference of circle:
C=2πr
here radius, r=4 cm and π=3.142
Put values in formula.
C=2(3.142)(4)
C=25.1 cm (Rounded to 1 decimal place)
Answer: Circumference of the circle is 25.1 cm (Rounded to 1 decimal place)
