The value of the y coordinate of any point on the x axis is always 0.
<u><em>Explanation</em></u>
Suppose, the co ordinate of any point is 
.
It means, the distance of the point from x-axis is '
' and distance from y-axis is '
'.
Now if the point lies on the x-axis, that means the distance of the point from x-axis will be 0. Thus, the value of '' will be 0.
So, the value of the y coordinate of any point on the x axis is always 0.
Answer: A
Step-by-step explanation:
The main parent functions are x, and x raised to the power of something (examples: 
, etc)
Chair=4x
lamp=x
table=4x-23
4x+x+4x-23=562
9x=585
x=585/9
x=65
4x=260
4x-23=237
10x + 35
If it is just the sum then it is this.
The angle of a tangent and a radius is a right angle.
The missing length would be the hypotenuse. Use the Pythagorean theorem to solve.
X = SQRT(12^2 + 16^2)
X = SQRT(144 + 256)
x = SQRT(400)
X = 20
