Answer:
C (x = 2)
Step-by-step explanation:
Since x is a non-negative number, A and B are eliminated.
This leaves C and D.
C: x = 2,
2 + 3 < 2^2
5 < 4 is false.
So C would be a counterexample.
Hope this helps!
Answer:
"The area of EFGH is always One-half of the area of the rectangle."
Step-by-step explanation:
<em>Graph is attached.</em>
<em />
The kite consists of 2 triangle, EFG and EHG.
The area of EFG:

where h is the height from F to EG
The area of EHG:

where
is the height from H to EG
We also know that h + h _1 is the width of the rectangle and EG is the length of the rectangle
Thus,
Area of Kite = 
Also, Area of rectangle is rectangle length * rectangle width.
Thus, area of kite is always half of that of rectangle, the third choice is right.
7x+3y=25
-2x-y=-8
7x+3y=25
(-2x-y=-8)3
7x+3y=25
-6x-3y=-24
x. =1
x=1
now you plug in that x value
-2(1)-y=-8
-2-y=-8
+2. +2
-y = -6
-1. -1
y = 6
(1,6)
Just inverse the fraction and you will find the reciprocal:
The reciprocal of 15/7 is 7/15
The reciprocal of 7/12 is 12/7
