The output or y-value when you input x-4 into the function y = 2x + 6 is 2(x-4) + 6 = 2x - 8 + 6 = 2x - 2.
If:xy = x2 + y2 + 2xyThen:x2 + xy + y2 = 0Do you want to solve it for x?x2 + xy + (y/2)2 = (y/2)2 - y2(x + y/2)2 = y2/4 - y2x + y/2 = ± √(-3y2/4)x = -y/2 ± y√(-3) / 2x = (-y ± yi√3) / 2
The sum of adding 4 to itself 23 times is 96. This can be calculated by multiplying 4 by 24, as each addition of 4 counts as one less than the total number of 4s being added. Therefore, 4 x 24 equals 96.

The browser used for posting questions on this site is mostly useless for mathematical questions since it strips out most symbols. It is, therefore, not possible to tell where the equality (or inequality) symbol in the function lies and so determine the domain or range.
If you mean: y = 2x and 2y = -x+4 then they are positive and negative straight line equations
If you mean: y=2x+4 and x+2y=12 => y=-1/2x+6 which means that they are perpendicular to each other.
If you mean: y = 2x-4 then it is equal to a straight line equation
y=2x+4 is in slope intercept form

The slope of y = 2x - 4 is 2. (y = mx + b, where m is the slope, in this case 2.)
The output or y-value when you input x-4 into the function y = 2x + 6 is 2(x-4) + 6 = 2x - 8 + 6 = 2x - 2.
If you mean: y = 2x-4 and (1, 5) then the parallel equation is y = 2x+3
The sum of adding 4 to itself 23 times is 96. This can be calculated by multiplying 4 by 24, as each addition of 4 counts as one less than the total number of 4s being added. Therefore, 4 x 24 equals 96.
