Because when y = x+3 it is a straight line equation with a slope of 1 and a y intercept of 3
x = -2 and y = 3
8
(-3,-4)
It equals x+5y simplified
That is irrelevant, there is not possible way y=xy, and there is no possible way xy=x.
No it equals 6 because x and y equal 1 in themselves
what is c, x + 2y, x+y equal to or greater than 8, x equal to or greater than 3, y equal to or greater than 0.
x = -2 and y = 3
If x+y = 3 and y times x = 2 then y = 1.
You can do the equation Y 2x plus 3 on a graph. On this graph the Y would equal 5 and X would equal to 0.
X/3+Y There is no answer unless its equal to something X/3+Y=0 for example, or you have a value for the variables (1)/3+(2).
That would be very hard to answer, because it's not. (x + y)2 = x2 + y2 + 2xy
8
y = x2 + 8x + 15 = (x + 3)(x + 5). When y = 0, one or other of the two factors must equal zero; that is, x = -3 or -5, when y = 0.
(-3,-4)
Assuming y' is dy/dx, y = x^4/4 + yx^2
(x^2 - y^2)
