What is y equals x plus 4?
y=x+4 If you are tring to get "x" alone, you would do this: y=x+4 -4 -4 -------- y-4=x If you are trying to get "y" alone, then y=x+4 is your answer. Y and X represent the 'Unknown Number'. For example, Y might mean the number 6 and X means the number 2, so then Y equals the same amount as X + 4 does which, in my example, is 6 but the numbers value to the letters (what the letter replacing the number is) changes from equasion to equasion. Generaly, somewhere written on the sheet it may say Y = 6 so then you would have to find out what X means, which in my example, is 2.
What are the coordinates of the y intercept?
They are at (0, y) on the Cartesian plane where y is the vertical y axis. For any function you would have to solve the function for the value of y when x is zero - and then the coordinates would be (0,y) For the x (horizontal) axis, which is equivalent to the function y = 0, they would be (0,0), i.e. when x is zero, y is zero.
How do you get variable alone in 4y equals 3?
4y/4 = 3/4 y = 3/4
How would you solve y squared equals 11y?
y*y = 11y Divide both sides by y: y = 11
What happens to z when x is doubled and y stays the same?
That would depend on the relationship between x, y, and z.That would depend on the relationship between x, y, and z.That would depend on the relationship between x, y, and z.That would depend on the relationship between x, y, and z.
