Question

Which of the following is an example of a constant?
A. y
B. square root of four
C. 5 – x
D. x = y

some one please help

Answer 1

variables are the letters
constants are the numbers by themselves

reason it is called a constant is because the number does not change.

variable can be different numbers depending on the problem.

Answer 2

So for example
y=x
This equation varies depending on what x equals
So if x equals 7 then y equals 7
If x equals 8 y equals 8
There is no set value for x. x can literally equal anything and therefore so can y
So which example is a constant number?

Answer 3

Just give an educated guess

Answer 4

Constants do not have any variable terms, i.e. x and y.
