Answer:
k = 11
Step-by-step explanation:
Given the points are collinear then the slopes between consecutive points are equal.
Using the slope formula
m = 
with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (1, - 1)
m = 
= 
= 
Repeat with another 2 points and equate to
with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (k, 4)
m = 
, then
= ( cross- multiply )
k - 1 = 10 ( add 1 to both sides )
k = 11

Answer:
I think it’s 240
Step-by-step explanation:
Hope this helps
I can get it into standard form of that certain conic section by completing the square
<span>
</span>
(x^2-2x)+(y^2-4y)-31=0
<span>
</span>
(x^2-2x+1-1)+(y^2-4y+4-4)-31=0
<span>
</span>
(x-1)^2-1+(y-2)^2-4-31=0
<span>
</span>
(x-1)^2+(y-2)^2-36=0
<span>
</span>
(x-1)^2+(y-2)^2=36
<span>
</span>
(x-1)^2+(y-2)^2=6^2
in form
(x-h)^2+(y-k)^2=r^2
r=radius
so how wide it is is the diameter which is 2 times of radius
6=radius
6 times 2=12
12 inches I assume if the units in equation is in inches
Answer: 24
Step-by-step explanation:
Basically you just need to add them simply breaking them up then adding them
