Hello!
On the graph, when the X values are between 4 and 8, they are being constant. The X values between 4 and 8 are constant because the line shown between 4 and 8 on the graph show the line as a straight line. It is not going up nor is it going down, so you can conclude that the X values are not increasing or decreasing.
I hope this helps!

The domain is A. all real numbers except 0. The domain will always be all real number except what the denominator is equal to. To find the domain, you would set the domain to zero and solve for x. So it would be x^2=0 and solve. Square root the equation. The square root of zero is 0 leaving you with x=0. Giving you the answer A. all real numbers except x=0.
Hope this helped.
Step-by-step explanation:
(10, 9), (5 , 4)
Use the distance formula to determine the distance between the two points.
Distance
=√(x2−x1)² +(y2 - y1)²
Substitute the actual values of the points into the distance formula.
√(5−10)² +(4−9)²
Simplify.
5√2
Exact Form:
5√2
Decimal Form:
7.07106781

m□ebd=4 x-8 and m□ebc=5 x+20
This is solvable only if e b is the initial side and b d and b c lies on opposite side of each other and lies on a line i.e c,b,d are Collinear.
∠ebd and ∠ebc will form a linear pair.The meaning of linear pair is that angles forming on one side of a straight line through a common vertex which are adjacent is 180°.
i.e
∠ ebd + ∠ebc = 180°
4 x- 8 + 5x + 20= 180°
adding like terms
⇒ 9 x +12 =180°
⇒ 9 x = 180° - 12
⇒ 9 x = 168°
⇒ x =( 168/9)°=(56/3)°
now m□ebc =5 x +20
= 5 × 56/3 + 20
= 280/3 + 20
=340/3
m□ebc=( 340/3)°
So, solution set is x =(56/3)° and m□ebc =(340/3)°
