How do you identify if the given equation is function or not?
A function is an equation (a relation) which has only one y-value for every x-value. If a single x-value has more than one y-value, the equation is no longer called a function.
What is the value of x in the equation x y 30 when y 15?
If you mean: x+y = 30 and the value of y is 15 then the value of x is also 15
What is the value of y in this equation 0.017y 5.1?
300
In the equation y 3x 1 what is the value of y when x equals 3?
If you mean: y = 3x+1 then the value of y will equal 10
What function has an output value of 7 for an input value of 4?
You are basically looking for an equation with an x and y value where when 4 is set as x, y would equal 7. An equation of this is: 3 + x = y when x = 4, then y = 3 + 4 = 7
What value of y makes this equation true when x equals 3?
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.
What value for y makes the sentence true?
Y for Yes
What is 23 plus y equals 14?
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
What is the answer to y equals x?
That depends what the question is! The equation is true whenever x and y have the same value; false otherwise.
An equation for a line in the xy-plane allows you to find the value of y given x?
True.
What is number y?
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.
Does (0 -5) make the equation y -6x -5 true?
if equation is y = -6x -5 then when x = 0 y = -5 which is true
Is an equation a function if it has more than one x value for every y value?
Yes. If it had more than one y value for each x value, on the other hand, it would not. A function is "Something that has a value depending on some input". Now an equation is something like Function(of x) = 0. You could say this equation has 2 possible values, True or False. This is not the same thing as saying there are two values of x to make the zero. So y=x2 has two values of x for every y. Generally, nobody would say y=x2 is a function. Except in the sense that it the equation is true for some values of x and y, and false for any others.
What is the solution to the equation y equals -2.5?
y = -2.5 is a equation. And solution to the equation is finding the value of the variable. If we see the equation y is already equal to -2.5 which is the solution to the equation.
How do you know if an order pair is on the line of an equation?
Substitute the first of the ordered pair wherever x appears in the equation and the second value wherever you have y. Evaluate the equation. If it is true, then the point is on the line and if not, it is not.
If the equation is x equals 2 what is y?
That makes no sense, there is no y in the equation so y cannot equal anything.
What is -8 plus 3y equals 12?
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
