1. how do u solve this?

m= (x+y+z)/3 ...given m = x/3 + y/3 + z/3 ....distribute m = x/3 + z/3 + y/3 + -(y/3) ...subtract "y/3" from right side of the problem... m - y/3 = x/3 + z/3 ...where we should now be at -(m) + m - y/3 = x/3 + z/3 + -(m) ....subtract "m...

4. Can someone solve for m for me? Just to check my answer?

x = y - m(y - z) x - y = -m(y - z) {subtracted y from both sides} -x + y = m(y - z) {divided both sides by -1} -x + y --------- = m {divided both sides by y - z} y - z http://www.algebrahouse.com

8. Using derivative method 1. Let xy+yz+zx=1 and x,y, z belongs to [-1,1]. Find max and min value of M= x^2+y^+z?

Min is at x = y = 1 - √2 and z = -1 (M = 5 - 4√2) Max is at x = y = 1, z = 0, (M = 2) also at x = -1, y = -1, z= 0, (M =2)
