What is y when x is three?
This question cannot be answered without the whole equation: If the equation is y = 2x, then y = 6 for x = 3. If the equation is y = x + 2, then y = 5 for x = 3. If the equation is y = 99/x, then y = 33 for x = 3. If you can provide the complete equation, your question could be answered more precisely.
How can you determine if an ordered pair is a solution to an equation?
plug the x coordinate in the x part of the equation and plug the y coordinate in the y's part of the equation and solve
What is a function that is equal to twice its derivative?
Assuming function of one variable... Want y[x] s.t. y''[x] =y[x] The characteristic equation is r^2 = 1. r = (+/-) 1 So, e^(x*1) and e^(x * -1) work. To get full generality, multiply them by any constants A,B and add. y[x] = A e^x + B e ^(-x) y'[x] = A e^x - B e ^(-x) y''[x] = A e^x + B e ^(-x) = y[x]
What is the equation to 2 units down of the graph of y equals x?
y=x-2
What is the standard form of the equation y equals -x plus 1?
X-y=1
What is the meaning of y-intercept is twice the x-intercept?
y intercept is value of y when x = 0 x intercept is value of x when y = 0 if y intercept is twice x intercept then its value is twice as high Mathematically, the standard form equation is y = mx + b where m = slope and b = y intercept for x intercept let y = 0 0 = mx + b x = -b/m = 1/2 y intercept = 1/2 time b m = -2 y = -2x + b is the equation
Twice the sum of x and y and The sum of twice x and y?
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
Which linear equation represents the statement the value of y is twice the quantity of 3 less than x?
It works out as: y = x-6
What is the difference between twice the sum of x and y and the sum of twice x and y?
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
What does the equation y x - x a?
The equation y x - x a is an algebraic equation that many learn in school, which involves numbers as well as letters. The equation y x - x a would be x (y-1).
What points are on the line given by the equation y equals 2x?
All points whose y-coordinate is twice its x-coordinate.

Is the following equation solvable - y equals y plus x?
If y = y + x then x must be 0 Otherwise the equation is meaningless.
1 If y is a function of x in the equation y equal 2x minus 7 then write a true statement?
The dependent variable, y, is equal to 7 less than twice the independent variable, x.
The perimeter of a rectangular lot is 156 meters the length is twice the width write the equation that describes the situation?
2(x + y) = 156 x = 2y Here x = length of rectangle and y = width
What is the intercept of the equation y equals -x?
The 'x' and 'y' intercepts of that equation are both at the origin.
Which is a solution of the equation 2x- y equals 0?
2x-y=0 -y=-2x y=2x A line going through the origin and having a slope of 2. Sample answers are y is twice as much as x. y=2 when x=1
