B. Number lines from minus five by increament of one from left to right and each tick mark is labeled. Shaded part from open circle at minus three to infinity
C. Number lines from minus five by increament of one from left to right and each tick mark is labeled. Shaded part from minus infinity to close circle at minus three
D. Number lines from minus five by increament of one from left to right and each tick mark is labeled. Shaded part from minus infinity to open circle at minus three

Answer: Choice A
Explanation
Let's solve for x.
The inequality sign flips whenever we divide both sides by a negative number.
The number line graph will have a closed filled in circle at -3 and shading to the right. This will visually mean "The solution set is either x = -3 or x > -3". In other words, we can pick -3 or larger.
The diagram is shown below.
The diagram matches with answer choice A

Answer:28
Step-by-step explanation: 6.4x6.4 = 40.96
3.6x3.6=12.96
Final answer:
To evaluate the expression (6.4)² - (3.6)², square each of the numbers and then subtract the square of 3.6 from the square of 6.4 to give a result of 28.
Explanation:
The question asked is mathematics related and it requires to evaluate an expression: (6.4)² - (3.6)². This is a simple arithmetic problem that involves squaring numbers and subtraction.
Firstly, squaring a number means multiplying the number by itself. Hence, (6.4)² equals to 6.4 * 6.4 which gives 40.96. Similarly, (3.6)² equals to 3.6 * 3.6 which gives 12.96.
Then, subtract the squared number of 3.6 from the squared number of 6.4. That is: 40.96 - 12.96, and you'll have your answer, which is 28.

Answer:
Option A is correct.
x – 4y = 8
Step-by-step explanation:
Using point slope form:
The equation of line is given by:
....[1]
where, m is the slope.
As per the statement:
The point passes through the line are:
(-4, -3) and (12, 1)
Using Slope(m) formula:
Substitute the given values we have;
Substitute the value of m and (12, 1) in [1] we have;
Multiply both sides by 4 we have;
Add 4 to both sides we have;
⇒
Multiply both sides by -1 we have;
⇒
Therefore, the standard form of the equation for this line is, x – 4y = 8
slope(m) = (1 - (-3) / (12 - (-4)
slope(m) = (1 + 3) / (12 + 4)
slope(m) = 4/16 = 1/4
y - y1 = m(x - x1)...using (12,1)
y - 1 = 1/4(x - 12)
y - 1 = 1/4x - 3
y = 1/4x - 3 + 1
y = 1/4x - 2
-1/4x + y = -2...multiply by -4
x - 4y = 8 <=== here it is

we notice that the square is tilted diagnaol
remember that the legnths of the diagonals of a square are equal
therefor the distance between the points (5,1) and (-1,1) is the same as the ohter diagonal (distance is 6)
the other point is probably that disance up or the y vairable
(2,-2)+6 on the y
-2+6=4
