What is the value of y in x equals -6 and x plus y equals 0?
y = 6
Given y is inversely proportional to x If the difference in the values of y when x 2 and x 6 is 5 How do i find the value of y when x 4?
As y is inversely proportional to x, the equation relating x to y is given by: y = k/x where k is the constant of proportionality. Using this we can find expressions for the value of y when x = 2 and x = 6 in terms of k: x = 2 → y = k/2 x = 6 → y = k/6 The difference between these is k/2 - k/6 = 3k/6 - k/6 = 2k/6 = k/3 But this, we are told is 5; thus: k/3 = 5 → k = 15 Thus y = 15/x Now that we have found the equation relating x to y, we can plug in the value for x = 4 and find the value of y: The value for y when x = 4 is y = 15/4 = 3.75
Which function has a y-value of 6 if the x -value is 3?
3
What does x - y?
In expressions such as "x-y", both "x" and "y" can have any value. The value of "x-y" will depend on what the value of "x" and the value of "y" are.
What is the y coordinate of 6 in the linear equation x equals 7-y?
Assuming 6 refers to the value of x, the y coordinate is 1
