x-2y=0
x=2y
The solution set is the set of all (x,y) such that x=2y
(2x)ysquared
Whooop!
y = 2x - x2y = 0Since both quantities on the right side are equal to 'y', they're equal to each other.2x - x2 = 0x (2 - x) = 0x = 0and2 - x = 0x = 2The two points of intersection are (0, 0) and (2, 0) .
It is -2y + x2y - 8, which is an expression that cannot be simplified further, not can it be evaluated.
You will get nonsense. You cannot plug x2y + 4 into anything!
4 (apples) plus 3 (apples) = 7 (apples). 4 (cows) + 3 (cows) = 7 (cows) 4 (x2y) + 3 (x2y) = 7 (x2y)
15 percent 0 equals 0; 0 percent 15 equals 0. Both the above are true
x2y = k (constant) so 36 x 2 ie 72 is the constant. If x = 3 then y = 72/9 = 8
yes
xy
maybe
