X2 (5)2 = 25 (- 5)2 = 25 An identity, almost, as any number put into this expression will yield the same value.
equivalent expression
The algebraic expression of: -x-1y has the same value as -x-y
Replace each variable in the expression by its value and then find the value of the expression.
An equivalent expression.
If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.
You can replace a variable with an equal value or expression. Just make sure the same variable always gets the same value or expression.
