The given equation is a wave function. When plotted, the graph is shown in the attached picture. However, the unit is in degrees instead of radians. A unit of π is equivalent to 180°. This plot could determine one variable if the other is given.
The given quadrilateral is a kite.
Given: Point A (2, 4), B (-2, -5), C (7, -1) and D (7, 4)
Firstly, we find the distance between AD and DC
AD = 
⇒ AD = 
⇒ AD = 5
DC = 
⇒ DC = 
⇒ DC = 5
Hence, AD = DC = 5
Now, find the distance between AB and BC
AB = 
⇒ AB = 
⇒ AB = 
⇒ AB = 
BC = 
⇒ BC = 
⇒ BC = 
⇒ BC = 
Hence, AB = BC = √97
In the given quadrilateral, the two pair is of equal length and these sides are adjacent to each other.
Hence, it follows the property of kite.

Answer:
8x+8y
Step-by-step explanation:
red roses = 8 × x = 8x
white roses = 8 × y = 8y
total= 8x+8y
<span>y=2\3x-17and 4x-6y=-7 implies - 6y= - 4x -7, and then y= (-4/-6)x +7/6 and so
y=2/3x+7/6
but when we have y=ax+b and y=a'x+b', the two lines are parallels if a=a', in our case 2/3=2/3 the lines are parallel

C
the square of the sum of 7 times x and 3 is expressed as
7x + 3 ← the sum of 7 times x and 3
(7x + 3)² ← the square of the sum of 7 times x and 3
4 times the difference of x and 1 is expressed as
x- 1 ← the difference of x and 1
4(x - 1) ← 4 times the difference of x and 1
putting it all together gives
(7x + 3 )² / 4(x - 1 ) → C
