Answer:
rhombussquarerectanglesquareStep-by-step explanation:
It is convenient to look at the differences of end point coordinates.
For a square, the values will be interchanged and one negated.
For a rhombus, the dot product will be zero.
For a rectangle, their sum of squares (diagonal length) will be the same.
__
1. VX = X - V = (11 -3, 4 -0) = (8, 4)
WY = Y -W = (8 -6, 0 -4) = (2,-4)
The numbers are different, so it is not a square. The dot product is ...
(8)(2) + (4)(-4) = 16 -16 = 0
So, the figure is a rhombus.
__
2. LN = (6 -1, 3 -2) = (5, 1); MP = (4 -3, 0 -5) = (1, -5)
The figure is a square.
__
3. HK = (12 -1, 0 -3) = (11, -3); JL = (3 -10, -3 -6) = (-7, -9)
The lengths of the diagonals are ...
√(11^2 +3^2) = √130 and √(7^2 +9^2) = √130
Diagonals are the same length, so the figure is a rectangle.
__
4. EG = (-2 -(-4), -1 -3) = (2, -4); FH = (-5 -(-1), 0 -2) = (-4, -2)
The figure is a square.

Answers
Answer:
x = 45/17
Step-by-step explanation:
We can move all x to 1 side and all the numbers to another. You can add 8.7 on both sides and get that 2.3x = 0.8x + 4.5. Next, we subtract by 0.8x on both sides to get that 1.7x = 4.5, where we can then divide by 17/10 on both sides to get that x is equal to 45/10 * 10/17, so that means that x = 45/17.

Direct Relationship
Two variables x and y have a direct relationship if the function that relates them is written as:
y = kx
Where k is the constant of proportionality.
The graph of such function is a straight line passing through the origin (0,0).
The graph does not show a direct relationship because it has the shape of a curve, not a straight line.

[tex]-\frac{x^{5} }{2} - x^{2} -6[/tex]
Step-by-step explanation:
[tex]-\frac{x^{5} }{2}[/tex] has the greatest degree and is, therefore, the first term in the equation.
-[tex]x^{2}[/tex] has the second greatest degree and is the second term in the equation.
-6 has the lowest degree so it is the last term.

Answer:
(x, y) = (-4, 3)
Step-by-step explanation:
x + y = -1 $|Rightarrow$ x = -1 - y
x - y = -7
Substituting the value of x (first equation) into the second equation, we get:
(-1 - y) - y = -7.
Simplifing, we get:
-1 -2y = -7
-2y = -6
y = 3.
Now that we know the value of y, we can solve the value of x by substituting y into the first equation. We get:
x = -1 - 3
x = -4

-4(p-212)=44 can someone please help with this question
Answers
Answer:
my algebra calculator says the answer is
p=201
Answer:
p = 201
Step-by-step explanation:
In this question, you would solve for the variable "p".
Solve:
-4(p - 212) = 44
Use the distributive property to distribute the -4.
-4p + 848 = 44
Subtract 848 from both sides to get -4p by itself.
-4p = -804
Divide both sides by -4 to get "p" by itself.
p = 201
Your final answer would be p = 201
