What does x mean in a math equation?
x is a variable. You do not have to know what its value is. In that equation you have to find the value of x, so if you already know what x stands for then you know the answer
What is a positive gradient in math?
A positive gradient is a characteristic of a function whose value increases as the value of the argument increases. So, if y is a function, f(x), of x, then an increase in the value of x is accompanied by an increase in the value of y.
When x 8 what is the value of 5x?
Well, isn't that just a happy little math problem! When x is multiplied by 8, we get 8x. So, if we want to find the value of 5x, we simply multiply 5 by the value of 8x. That gives us 40x. Just remember, there are no mistakes in math, only happy accidents!
What is the constant of proportionality in math?
If two variables, X and Y, are in direct proportion then Y = c*X for some fixed value c. This value, c, is the constant of proportionality for this relationship.
Math formula for period?
A function f(x) has period t if t is the smallest value such thatf(x+t) = f(x) for all x in the appropriate domain.
