(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
xy
yes
x2 + y - 49 = 0At the x-intercepts, y=0:x2 - 49 = 0(x+7)(x-7) = 0x = -7 and x = +7At the y-intercept, x=0:y - 49 = 0y = 49General Solutionset x=0 to find your y-intercept and set y=0 to find your x-intercept. That's how you will always find your intercepts, no matter what the equation is.Ex. So if you find that when x=0, y=a, then the y-intercept is at the point (0,a).Similarly, if you find that when y=0, x=b, then the x-intercept is at the point (b,0).You can solve any problem from here.
