Find the coordinates of the intersection of the diagonals
of parallelogram XYZW with vertices X(2, 2), Y(3, 6), Z(10, 6), and W(9,2). Hint: what do we know about
the diagonals of a parallelogram?
Answer:
We know the basic facts about parallelogram is The basic formula for calculating the area of a parallelogram is the length of one side times the height of the parallelogram to that side.
Step-by-step explanation:
The coordinates of the intersection of the diagonals of parallelogram XYZW is at (6, 4).
Parallelogram
A parallelogram is a quadrilateral in which opposite sides are parallel and equal. The diagonals of a parallelogram bisect each other.
Given parallelogram XYZW with vertices X(2, 2), Y(3, 6), Z(10, 6), and W(9,2).
The equation of diagonal XZ is:
[tex]y-2=\frac{6-2}{10-2} (x-2)\\\\y=0.5x+1[/tex]The equation of diagonal YW is:
[tex]y-6=\frac{2-6}{9-3} (x-3)\\\\y=-\frac{2}{3} x+8[/tex]The point of intersection is at:
0.5x + 1 = (-2/3)x + 8
x = 6. Hence y = 4
The coordinates of the intersection of the diagonals of parallelogram XYZW is at (6, 4).

A student bought 3 boxes of pencils and 2 boxes of pens for $6. He then bought 2 boxes of pencils and 4 boxes of pens for $8. Find the cost of each box of pencils and each box of pens.
Answer:
.
Step-by-step explanation:
Each box of pens are valued at $1.50, thus for 2 boxers it would be 1.50 x 2 = $3. Thus, 2 boxes of pens = $3. Each box of pencils cost $1. therefore 3 boxes of pencils valued at $1 each = to $3. Final equation $3 + $3 = $6 for the first purchase. Using the same numbers we valued the 2 boxes of pencils at $1 each = $1 pencil box + $1 pencil box = $2 for 2 boxes. Then 4 pen boxes valued at $1.50 each = to $1.50 x 4 = $6 Final equation $6pen + $2pencil = $8 final
v2+4v-21=0 (solve by factoring)
Answer: (v + 7)(v -3)
Step-by-step explanation:
(v +7)(v -3)
v x v = v^2
v x -3 = -3v
7 x v = 7v
7 x -3 = -21
v^2 -3v +7v -21 = v^2 +4v -21 = 0
Answer:
The answer is (v - 3)(v + 7).
Step-by-step explanation:
First, you have to elaborate it :
v² + 4v - 21 = 0
v² - 3v + 7v - 21 = 0
Next, you have to collect like terms :
v(v - 3) + 7(v - 3) = 0
(v - 3)(v + 7) = 0

Compare the function with the parent function. Without graphing, what are the vertex, axis of symmetry, and transformations of the given function?
y = 8x - 21 - 7
Answer:
The parent function is: y = x
First, here we have two types of transformations, and we could define them in a general way as:
if we start with a function f(x)
Vertical dilation/contraction: A vertical dilation/contraction of scale factor A (A is always positive) is written as:
g(x) = A*f(x)
Vertical translation:
We can write a vertical translation of A units upwards as:
g(x) = f(x) + A
And a vertical translations of A units down can be written as:
g(x) = f(x) - A.
In this case, the transformations are:
first, a dilation of scale factor 8.
Then a translation down of 21 units
then another translation down of 7 units.
y = 8*X - 21 - 7
y = 8*x - 28.
As this is a linear equation, there are no axis of symmetry, we only could have a line of symmetry along the same line y = 8*x - 28
Again, as this function is a linear equation there is no vertex.

Tell me everything you know about Pythagorean Theorem. Some things to include, but not limited to: Why is it that in some examples you have to subtract the square of a leg from the hypotenuse? Can this be used on every triangle? When might someone use this in real life as an adult?
Answer: Check below
Step-by-step explanation:
Okay so the Pythagorean Theorem was made by some old guy and the formula is a^2+b^2=c^2. You ALWAYS have to subtract the leg of the triangle when your finding a leg. You squareroot the square of the two legs if your finding the hypotnuse. The Theorem can be used to find any side of the triangle ONLY IF its a right triangle. An adult might use it in real life like when your an architect trying to find how much material you should use to make something thats in the shape of a right triangle.
