8x + y = -16 ;
3x - y = 5 ;
____________(+)
11x = -11;
x = - 11 / 11 ;
x = - 1;
y = -5 + 3 * ( - 1 ) = - 8.
In this case, we have a colored dot at -1 and a white dot at 3, then the interval notation for that graphed interval will be:
[-1, 3).
<h3>How to write the interval of values in the graph using interval notation?</h3>
First, remember that the symbols ( and ) are used for ends that do not belong to the interval.
For example, if our interval is 1 < x < 2
1 and 2 do not belong to the solution interval, thus, the solution interval is (1, 2).
While [ and ] are used when the ends belong. For example, in:
1 ≤ x ≤ 2
The interval notation is [1, 2]
And in:
1 < x ≤ 2
(1, 2]
And so on.
On the number line, the notation is:
- Colored dot: the point belongs to the interval.
- White dot: the point does not belong to the interval.
In this case, we have a colored dot at -1 and a white dot at 3, then the interval notation for that graphed interval will be:
[-1, 3).

Answer:
HIJK is a parallelogram because the midpoint of both diagonals is unique and intersect each other, which means the diagonals bisect each other.
Step-by-step explanation:
We are given the following in the question.
HIJK is a parallelogram.
So it satisfies the property of parallelogram.
- The diagonals of a parallelogram bisect each other.
- That is the intersection of the diagonals of the parallelogram is unique and divide the diagonals in two equal parts each.
Thus,
HIJK is a parallelogram because the midpoint of both diagonals is unique and intersect, which means the diagonals bisect each other.
Answer:
y < -1.2
Step-by-step explanation:
Hii,
4/3 < -8/3 y
To get y by itself, you need to divide by -8/3 on both sides...
4/3 divided by -8/3 is the same thing as...
4/3 x -3/8
(when dividing fractions, simply flip the second fraction and multiply straight across)
After that, you get -12/24 which is the same thing as -1/2.
Since you divided by a negative, the inequality sign flips.
So...
-1/2 < y
is...
y < -1/2
Hope this helps!
Answer:
444.
Step-by-step explanation:
The '4' is considered to be a string so if you print y you would get 444. The int means 'integral, ( I believe).
