You can find out the base by the following way.. Let us consider the example:
(25/3)=7
To find its base let as assume it has base r.. Now find the value of r by converting the nums in decimal:
(2r+3)/3=7 (As 25 in base r is equal to 2*(r^1) + 5*(r^0) in decimal)
2r+3=21
2r=21-3
2r=18
r=9
It is, in fact, an identity - which is an equation which is true for all values of the variable.
-4
There is no way to know unless you had an equation that gives the relationship between x and y. For example, if y=2x, then when x equals 99 or x equals 100, then the value of y has a difference of 2.
That is as far as you can go with that equation without knowing the values of "d," "h," or "m."
It is a straight line equation in the form of: y = x+5
When you can reverse the values in an equation and the answer is the same, this is referred to as commutivity. In this example, this is the commutative property of addition.
It is, in fact, an identity - which is an equation which is true for all values of the variable.
They are called the solutions or roots of the equations.

There are no exclude values of the equation, as given.

Find an equation of variation where y varies directly as x. One pair of values is y = 80 when x = 40
It is a quadratic equation and the values of x are: -1/2 and 6
There can be no answer. y = y is an identity - a statement that is true for all values of y. That leaves y = - 3 - x. It is not possible to solve one linear equation in two unknown variables (x and y). You can only rearrange the equation: for example, to x+y+3=0.
zeros values at which an equation equals zero are called roots,solutions, or simply zeros. an x-intercept occurs when y=o ex.) y=x squared - 4 0=(x-2)(x+2) (-infinity,-2)(-2,2) (2,infinity)
