Hmm
well, um
if -4 is a zero then if we subsitute -4 for x, we should get 0
so
0=(-4)²-(-4)-(2k+2)
0=16+4-2k-2
0=18-2k
2k=18
divide by 2
k=9
k=9
the value k is 9
Examples of this are:
2 and 
2 and 
4 and 
I'm guessing you have a work sheet going along with this which has actual images of containers. I've attached an example - if you can post the actual work sheet you're referring to I can edit this answer to correctly reflect your specific question.

Answer:
The arc measure, x, that the satellite can see is 160°
Step-by-step explanation:
Given that the two tangents intersect at a point outside the with circle center O
The angle formed between between the two tangent = 20°
The first arc formed is measured as x°, which is the arc opposite the point where the two tangents meet = The arc the satellite can see
The angle x is given by the relationship;
x = 2 × (90 - v/2)
Where;
v = The angle formed at the point where the two tangent meet = 20°
Therefore;
x = 2 × (90 - 20/2) = 2 × (90 - 10) = 2 × 80 = 160°
The arc measure, x, that the satellite can see = 160°.
Answer:
Table is attached
Step-by-step explanation:
We are given equation as

We will complete each column
First column:
we are given x=2 and we have to find y



Second column:
we are given y=3 and we have to find x



Third column:
we are given x=6 and we have to find y



Fourth column:
we are given x=0 and we have to find y



Fifth column:
we are given x=3 and we have to find y



Sixth column:
we are given y=0 and we have to find x



Seventh column:
we are given y=8 and we have to find x



now, we can complete table
