y = 100 - 4x ( a ) Find the value of y when x = 20.
It depends on the relationship between x and y.
It depends on what y is.
By the definition of continuity, since the limit and f(x) both exist and are equal (to 0) at each value of x, y=0 is continuous. This is true for any constant function.
The value of each angle put into a trigonometric function results in exactly one output value, because that angle represents a single set of x and y coordinates on the ray at the end of the unit circle. Since the trigonometric functions are all defined as the ratio of x and/or y and/or 1, there can only be one output value for each angle. However, the reverse is not true. As an example, tangent is defined as sine over cosine, or y over x. This means that an angle of theta plus 180 degrees generates the same value, because y over x is the same as -y over -x.
It might have been possible to give an answer if there had been an equation with the question!
In the equation x = 3, if x = 3, the equation is true, if x has any other value, it is not. The value of any other variable, such as y, is irrelevant. I would say that the answer is 0 because otherwise y is part of the equation which clearly it isnt.
It's a simple linear equation in 'y'.If you want to know what value of 'y' makes it true,you can find it like this:23 + Y = 14Subtract 23 from each side of the equation:Y = 14 - 23Y = -9
If: y = x+b then y-x = b
An excluded value is any x value that makes a function value y undefined. For a rational function, an excluded value is a value that makes the denominator equal to 0.
sometimes The statement X billion is greater than Y million is sometimes true when the values of X and Y are greater than zero. It is only sometimes true because it is not true when the value of Y is more than 1,000 times greater than X, but it is true when the value of Y is less than 1,000 times greater than X.
That depends what the question is! The equation is true whenever x and y have the same value; false otherwise.
-3
The value depends on the slope of the line.
Whatever you want it to be. In mathematics, letters are used for "variables", placeholders for a number which is not specified. Sometimes you are supposed to find a value of "y" so that a certain equation is true. For example, if y + 5 = 8, the only correct value for y is 3. In another equation, "y" may have a different value.
It's a simple linear equation in 'y'.If you'd like to know the value of 'y' that makes it true,you can find it as follows:3y - 8 = 12Add 8 to each side:3y = 20Divide each side by 3:y = 20/3
No question has been posed.If you'd like to know what value of 'y' makes the statement true, you can find it as follows:10y - 4 = 24Add 4 to each side:10y = 28Divide each side by 10:y = 2.8
