Y = 20
y = 100
3x+2y=43 where x=(-4+y)/2 =0.5y-2 3(0.5y-2)+2y=43 1.5y-6+2y=43 3.5y-6=43 3.5y=49 y=49/3.5 which is the same as (49x2)/7 =14
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 = 49
3/Y+7\Y=9 =>Y=10\9
The answer is 79. Since you know the values of x and y, you can simply substitute them into the equation to find the answer. x = 6 y = 7 5x + 7y = 5(6) + 7(7) = 30 +49 = 79
Y = 8 !
Y = 20

3x+2y=43 where x=(-4+y)/2 =0.5y-2 3(0.5y-2)+2y=43 1.5y-6+2y=43 3.5y-6=43 3.5y=49 y=49/3.5 which is the same as (49x2)/7 =14
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 = 49
3/Y+7\Y=9 =>Y=10\9
x2 / y = (6)2 /2 = 36/2 = 18
If by area you mean X*Y it would be -49 (or 49, if you assume area to be positive). (X=7, Y=-7) when X+Y^2=56 and X+Y=0.
