Answer:
2-√x
Step-by-step explanation:
(4-x)/(2+√x)*(2-√x)/(2-√x)
(4-x)(2-√x)/4-x
=2-√x
Answer:
X= A (Where A is a constant)
Step-by-step explanation:
Equation of y axis is X=0
Here it means that each point on y axis will have the same abcissa which is 0.
Now if you move parallel to the y axis the line will have an equation
X= A ; here A is an constant ( Can be both negative and positive depending on where the line is respect to the y axis)
here it means that each point on that line will have the same abcissa which is equal to a constant.
Answer:
![=\sqrt{x^2+y^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7Bx%5E2%2By%5E2%7D)
Step-by-step explanation:
The magnitude of this vector is the square-root of the sum of squares of the horizontal change and vertical change
Let the vector be t
magnitude of t will be
![t=\sqrt{x^2+y^2}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7Bx%5E2%2By%5E2%7D)
